EPrints 3 Reference: Directory Structure - Metadata Fields - Repository Configuration - XML Config Files - XML Export Format - EPrints data structure - Core API - Data Objects
This file contains configuration for indexing data objects.
In particular this has configuration for whether indexing is enabled and if so the following configuration rules:
$c->{indexing}->{freetext_min_word_size}- The minimum length a word in free-text field has to be to be indexed. The default is 3.$c->{indexing}->{freetext_stop_words}- Words that should not be indexed in free-text fields, as they are too common (e.g. and, are, the, you, etc.).$c->{indexing}->{freetext_seperator_chars}- Characters that separate two separate words in a free-text field (e.g. colon :, equals = hyphen -, full stop ., space , etc.). N.B. seperator was a typo in the codebase that cannot now be fixed for legacy reasons.
The file also contains the extract_words function for how individual words should be extracted from free-text. This may vary across different types of repository and some repositories may have edge cases they need to handle, so this has be purposefully designed as a user-defined function to facilitate bespoke requirements.
