Glasswall Word Search can be used to redact text from files and generates an XML report on the redacted file's details. See [Word Search & Redaction](/embedded-engine/embedded-engine-word-search-and-redaction).

This report includes details on the file size, the determined file type, the total number of text matches, and the location of each of the text matches.

## WordSearch

See [Loading a Glasswall Library](/embedded-engine/embedded-engine-python-loading-a-glasswall-library#wordsearch) for details on how to load the WordSearch library.

### Redact

Files can be redacted individually from a file path or in memory using the [redact_file](./8-Autogenerated%20Docs/libraries/word_search/word_search/word_search.md#redact_file) method, or all files in a directory can be redacted using the [redact_directory](./8-Autogenerated%20Docs/libraries/word_search/word_search/word_search.md#redact_directory) method.

#### Redact from file path to file path

```py
import glasswall


# Load the Glasswall WordSearch library
word_search = glasswall.WordSearch(r"C:\gwpw\libraries\10.0")

# Redact occurrences of the text "lorem" and "ipsum" within the input file, writing the redacted file to a new path
word_search.redact_file(
    input_file=r"C:\gwpw\input_redact\lorem_ipsum.docx",
    output_file=r"C:\gwpw\output\word_search\redact_f2f\lorem_ipsum.docx",
    content_management_policy=glasswall.content_management.policies.WordSearch(
        config={
            "textSearchConfig": {
                "@libVersion": "core2",
                "textList": [
                    {"name": "textItem", "switches": [
                        {"name": "text", "value": "lorem"},
                        {"name": "textSetting", "@replacementChar": "*", "value": "redact"},
                    ]},
                    {"name": "textItem", "switches": [
                        {"name": "text", "value": "ipsum"},
                        {"name": "textSetting", "@replacementChar": "*", "value": "redact"},
                    ]},
                ]
            }
        }
    )
)

```

#### Redact from file path to memory

`redact_file` returns an object with the attributes: "status" (int), "output_file" (bytes), "output_report" (bytes). The below example demonstrates assigning the variable `result` and checking the contents of the beginning of the redacted output_file and the output_report.

```py
import glasswall


# Load the Glasswall WordSearch library
word_search = glasswall.WordSearch(r"C:\gwpw\libraries\10.0")

# Redact occurrences of the text "lorem" and "ipsum" within the input file, writing the redacted file to a new path
result = word_search.redact_file(
    input_file=r"C:\gwpw\input_redact\lorem_ipsum.docx",
    output_file=None,
    content_management_policy=glasswall.content_management.policies.WordSearch(
        config={
            "textSearchConfig": {
                "@libVersion": "core2",
                "textList": [
                    {"name": "textItem", "switches": [
                        {"name": "text", "value": "lorem"},
                        {"name": "textSetting", "@replacementChar": "*", "value": "redact"},
                    ]},
                    {"name": "textItem", "switches": [
                        {"name": "text", "value": "ipsum"},
                        {"name": "textSetting", "@replacementChar": "*", "value": "redact"},
                    ]},
                ]
            }
        }
    )
)

assert result.output_file[:6] == b'PK\x03\x04\x14\x00'
assert result.output_report[:500] == b'<gw:WordSearchStatistics xmlns:gw="http://glasswall.com/namespace">\n\t<gw:DocumentSummary>\n\t\t<gw:TotalSizeInBytes>14292</gw:TotalSizeInBytes>\n\t\t<gw:FileType>docx</gw:FileType>\n\t\t<gw:TotalItemMatchCount>14</gw:TotalItemMatchCount>\n\t</gw:DocumentSummary>\n\t<gw:WordItem>\n\t\t<gw:Name>ipsum</gw:Name>\n\t\t<gw:ItemMatchCount>8</gw:ItemMatchCount>\n\t\t<gw:Locations>\n\t\t\t<gw:Location>\n\t\t\t\t<gw:Offset>120</gw:Offset>\n\t\t\t\t<gw:Page>0</gw:Page>\n\t\t\t\t<gw:Paragraph>0</gw:Paragraph>\n\t\t\t</gw:Location>\n\t\t\t<gw:Location>\n\t\t\t'

```

#### Redact from memory

```py
import glasswall


# Load the Glasswall WordSearch library
word_search = glasswall.WordSearch(r"C:\gwpw\libraries\10.0")

# Read file from disk to memory
with open(r"C:\gwpw\input_redact\lorem_ipsum.docx", "rb") as f:
    input_bytes = f.read()

# Redact occurrences of the text "lorem" and "ipsum" within the input file, writing the redacted file to a new path
result = word_search.redact_file(
    input_file=input_bytes,
    output_file=r"C:\gwpw\output\word_search\redact_m2f\lorem_ipsum.docx",
    content_management_policy=glasswall.content_management.policies.WordSearch(
        config={
            "textSearchConfig": {
                "@libVersion": "core2",
                "textList": [
                    {"name": "textItem", "switches": [
                        {"name": "text", "value": "lorem"},
                        {"name": "textSetting", "@replacementChar": "*", "value": "redact"},
                    ]},
                    {"name": "textItem", "switches": [
                        {"name": "text", "value": "ipsum"},
                        {"name": "textSetting", "@replacementChar": "*", "value": "redact"},
                    ]},
                ]
            }
        }
    )
)

assert result.output_file[:6] == b'PK\x03\x04\x14\x00'
assert result.output_report[:500] == b'<gw:WordSearchStatistics xmlns:gw="http://glasswall.com/namespace">\n\t<gw:DocumentSummary>\n\t\t<gw:TotalSizeInBytes>14292</gw:TotalSizeInBytes>\n\t\t<gw:FileType>docx</gw:FileType>\n\t\t<gw:TotalItemMatchCount>14</gw:TotalItemMatchCount>\n\t</gw:DocumentSummary>\n\t<gw:WordItem>\n\t\t<gw:Name>ipsum</gw:Name>\n\t\t<gw:ItemMatchCount>8</gw:ItemMatchCount>\n\t\t<gw:Locations>\n\t\t\t<gw:Location>\n\t\t\t\t<gw:Offset>120</gw:Offset>\n\t\t\t\t<gw:Page>0</gw:Page>\n\t\t\t\t<gw:Paragraph>0</gw:Paragraph>\n\t\t\t</gw:Location>\n\t\t\t<gw:Location>\n\t\t\t'

```

#### Redact files in a directory

`redact_directory` returns a dictionary of file paths relative to the input_directory, and an object with the attributes: "status" (int), "output_file" (bytes), "output_report" (bytes). The below example demonstrates assigning the variable `results` and checking the keys and values of the `results` dictionary.

```py
import glasswall


# Load the Glasswall WordSearch library
word_search = glasswall.WordSearch(r"C:\gwpw\libraries\10.0")

# Redact occurrences of the text "lorem" and "ipsum" within each file in the input_directory, writing the redacted file
# to a new path in the output_directory
results = word_search.redact_directory(
    input_directory=r"C:\gwpw\input_redact",
    output_directory=r"C:\gwpw\output\word_search\redact_directory",
    content_management_policy=glasswall.content_management.policies.WordSearch(
        config={
            "textSearchConfig": {
                "@libVersion": "core2",
                "textList": [
                    {"name": "textItem", "switches": [
                        {"name": "text", "value": "lorem"},
                        {"name": "textSetting", "@replacementChar": "*", "value": "redact"},
                    ]},
                    {"name": "textItem", "switches": [
                        {"name": "text", "value": "ipsum"},
                        {"name": "textSetting", "@replacementChar": "*", "value": "redact"},
                    ]},
                ]
            }
        }
    )
)

assert list(results.keys()) == ['lorem_ipsum.docx', 'lorem_ipsum.pptx']
assert all(result.status == 1 for result in results.values())

```

#### Redact files in a directory that may contain unsupported file types

The default behaviour of the Glasswall Python wrapper is to raise the relevant exception (see: [glasswall.libraries.word_search.errors](./8-Autogenerated%20Docs/libraries/word_search/errors/errors.md) if processing fails. Passing `raise_unsupported=False` will prevent an exception being raised and can be useful when working with a directory containing a mixture of both supported and unsupported file types when it is desirable to process as many of the files as possible instead of terminating on the first failure.

The below example input directory contains the same two files in the above example as well as a file with an unsupported file format: `python-package.yml`. We can inspect the key value pairs in the `results` dictionary and see that the object returned for the `python-package.yml` file returned a `status: 0`, a failure. The `output_file` attribute is empty bytes, and the `output_report` bytes is populated with a report that includes an `IssueItem` describing the problems encountered while attempting to redact the file: `File contents could not be accessed`.

```py
import glasswall


# Load the Glasswall WordSearch library
word_search = glasswall.WordSearch(r"C:\gwpw\libraries\10.0")

# Redact occurrences of the text "lorem" and "ipsum" within each file in the input_directory, writing the redacted file
# to a new path in the output_directory
results = word_search.redact_directory(
    input_directory=r"C:\gwpw\input_redact_with_unsupported_file_types",
    output_directory=r"C:\gwpw\output\word_search\redact_directory_unsupported",
    content_management_policy=glasswall.content_management.policies.WordSearch(
        config={
            "textSearchConfig": {
                "@libVersion": "core2",
                "textList": [
                    {"name": "textItem", "switches": [
                        {"name": "text", "value": "lorem"},
                        {"name": "textSetting", "@replacementChar": "*", "value": "redact"},
                    ]},
                    {"name": "textItem", "switches": [
                        {"name": "text", "value": "ipsum"},
                        {"name": "textSetting", "@replacementChar": "*", "value": "redact"},
                    ]},
                ]
            }
        }
    ),
    raise_unsupported=False
)

assert list(results.keys()) == ["lorem_ipsum.docx", "lorem_ipsum.pptx", "python-package.yml"]
assert [result.status for result in results.values()] == [1, 1, 0]

print(results["python-package.yml"].__dict__)
# {'status': 0,

#### Redact files in a directory conditionally based on file format

The example below demonstrates redacting of only docx and pptx files from a directory that also contains other unsupported file types.

```py
import os

import glasswall


# Load the Glasswall Editor library
editor = glasswall.Editor(r"C:\gwpw\libraries\10.0")

# Load the Glasswall WordSearch library
word_search = glasswall.WordSearch(r"C:\gwpw\libraries\10.0")

input_directory = r"C:\gwpw\input_redact_with_unsupported_file_types"
output_directory = r"C:\gwpw\output\word_search\redact_directory_file_format"

# Iterate relative file paths from input_directory
for relative_file in glasswall.utils.list_file_paths(input_directory, absolute=False):
    # Construct absolute paths
    input_file = os.path.join(input_directory, relative_file)
    output_file = os.path.join(output_directory, relative_file)

    # Get the file type of the file
    file_type = editor.determine_file_type(
        input_file=input_file,
        as_string=True,
        raise_unsupported=False
    )

    # Protect only doc and docx files
    if file_type in ["docx", "pptx"]:
        # Redact occurrences of the text "lorem" and "ipsum" within the input file, writing the redacted file to a new path
        word_search.redact_file(
            input_file=input_file,
            output_file=output_file,
            content_management_policy=glasswall.content_management.policies.WordSearch(
                config={
                    "textSearchConfig": {
                        "@libVersion": "core2",
                        "textList": [
                            {"name": "textItem", "switches": [
                                {"name": "text", "value": "lorem"},
                                {"name": "textSetting", "@replacementChar": "*", "value": "redact"},
                            ]},
                            {"name": "textItem", "switches": [
                                {"name": "text", "value": "ipsum"},
                                {"name": "textSetting", "@replacementChar": "*", "value": "redact"},
                            ]},
                        ]
                    }
                }
            )
        )

```
