fingerprint.ini

The fingerprint.ini config file, located at /etc/squirro/fingerprint.ini configures the workings of the fingerprint service. That service is responsible for the management of Smart Filters.

Options

The following options are configured in the fingerprint section.

Key	Usage	Default
max_contributing_items	Number of contributing items (definitions) that are considered for the Smart Filter training. Only the latest entries are considered.	20
min_feature_count	Number of times a feature (extracted token) needs to be present in the training text before it is included in the Smart Filter. See Improving Relevance in the reference for background information on this setting.	0
Phrase Detection
phrase_detection	Whether phrase detection is enabled. Set to “false” to disable. Phrase detection tries to extract multi-word tokens. As an example then instead of extracting two terms “income” and “statement”, the Smart Filter might contain of one term “income statement”.	true
phrase_length	How many terms are included in phrases.	2
max_phrases_per_language	The maximum number of phrases that are extracted for any language.	5
min_phrase_count	Number of times a phrase has to be present for it to be included in a Smart Filter.	2
