Back to cfg.d

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.).

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.
