AND

Base Combining Provider Grooper.Extract

Collation provider that returns results only when each extractor produces at least one match.

Remarks

The AND collation provider is used to combine the results of multiple extractors such that a positive result is only returned if all (or a minimum number of) extractors produce a hit.

This is especially useful for:

  • Classification rules: Where the presence or absence of certain features determines document classification.
  • Data extraction: When you need to ensure that multiple conditions are met before returning a result.

How it works

  • Each extractor is executed on the input.
  • If all extractors (or at least the number specified by 'MinimumHits') produce a match, the provider returns a result.
  • If 'SamePageOnly' is enabled, all required matches must occur on the same page.
  • The output can be either a single combined instance or the individual child values, depending on 'ReturnChildValues'.

Example

Suppose you have three extractors: A, B, and C. The AND provider will only return a result if all three extractors find at least one match (or if 'MinimumHits' is set to 2, at least two must match). If 'SamePageOnly' is enabled, the matches must all occur on the same page.
