The text field’s query analysis chain, on the other hand, is more limited. Position gaps (e.g., stop words) get ignored it’s not (yet) supported for the gap to be significant. However, do not use FlattenGraphFilterFactory as it will interfere with ConcatenateGraphFilterFactory. It can have multi-word synonyms and use WordDelimiterGraphFilterFactory for example. The text field’s index analysis chain, aside from needing ConcatenateGraphFilterFactory at the end,Ĭan otherwise have whatever tokenizer and filters suit your matching preferences. Recommended field settings: omitNorms=true, omitTermFreqAndPositions=true and postingsFormat=FST50. Set preservePositionIncrements=false on that filter.
Recommended field settings: set docValues=true.
ERYX THE TAGGER HOW TO
A unique key field (see Unique Key for how to define a unique key in your schema).To configure the tagger, your Solr schema needs 2 fields: Tens, perhaps hundreds of millions of names (documents) are supported, mostly limited by memory. The tagger does not yet support a sharded index. To get a sense of how to use it, jump to the tutorial below. The SolrTextTagger might be used on queries for query-understanding or large documents as well. System can be built with this as a key component. The tagger doesn’t do any natural language processing (NLP) (outside of Lucene text analysis) so it’s considered a "naive tagger",īut it’s definitely useful as-is and a more complete NER or ERD (entity recognition and disambiguation) It’s used for named entity recognition (NER). You can post text to this request handler and it will return every occurrence of one of those names with offsets and other document metadata desired. Given a dictionary (a Solr index) with a name-like field, The "Tagger" Request Handler, AKA the "SolrTextTagger" is a "text tagger".
