# CellEntityMatchLimitN

The maximum number of matches to return for the entities specified by the corresponding CellEntityN parameter. Named Entity Recognition searches for cell entity matches in the columns that have a header that match the HeaderEntityN entities (up to HeaderEntityMatchLimitN). After Named Entity Recognition finds this number of matches in those columns, it stops searching for further matches, so Named Entity Recognition does not return any further matches or spend time looking for them.

You might set this parameter if you want to see some matches for a particular entity, but would prefer to ignore further matches in favor of reducing the processing time.

If the CellEntityN parameter specifies multiple entities, using a wildcard or a comma-separated list, the limit applies separately to each entity. For example, the following configuration would permit up to five matches for English dates, and up to five for French dates, and so on:

    CellEntity0=pii/date/nocontext/eng,pii/date/nocontext/fre,pii/date/nocontext/spa
    CellEntityMatchLimit0=5

Named Entity Recognition applies the limit after post-processing, so any matches that are discarded by post-processing do not count towards the limit.

The limit applies only to matches in a single table. Named Entity Recognition resets the limit when it encounters a table delimiter.

Type: | Integer
Default: | No limit
Required: | No
Configuration Section: | Any section that you have defined for Named Entity Recognition settings
Example: | With the following configuration Named Entity Recognition returns a maximum of five matches for the `pii/date/nocontext/all` entity. `CellEntity0=pii/date/nocontext/all CellEntityMatchLimit0=5`
