# Enable Context Checks for the Name Grammar

You can turn on additional context checks for the names grammar, which can eliminate some false positive matches. This option adds a small performance penalty to the extraction speed, so it is turned off by default.

For example, with this option turned on, Named Entity Recognition does not match M Records as a name when it matches in the string A&M Records.

To enable this feature, you can use the following configuration.

    [Eduction]
    ContextCharsBeforeMatch=5
    ContextCharsAfterMatch=5
    PostProcessingDefaultParameters=LuaParams

    [LuaParams]
    IDOL_PXI_NAME_CHECK_CONTEXT=TRUE

Alternatively, you can set `IDOL_PXI_NAME_CHECK_CONTEXT` as an environment variable.
