SolrSynonymParser (Lucene 10.5.0 common API)
Description: declaration: package: org.apache.lucene.analysis.synonym, class: SolrSynonymParser

Package org.apache.lucene.analysis.synonym

# Class SolrSynonymParser

java.lang.Object
org.apache.lucene.analysis.synonym.SynonymMap.Builder
org.apache.lucene.analysis.synonym.SynonymMap.Parser
org.apache.lucene.analysis.synonym.SolrSynonymParser

public class SolrSynonymParser extends SynonymMap.Parser
Parser for the Solr synonyms format.

1. Blank lines and lines starting with '#' are comments.
2. Explicit mappings match any token sequence on the LHS of "=>" and replace with all alternatives on the RHS. These types of mappings ignore the expand parameter in the constructor. Example:

   > i-pod, i pod => ipod

3. Equivalent synonyms may be separated with commas and give no explicit mapping. In this case the mapping behavior will be taken from the expand parameter in the constructor. This allows the same synonym file to be used in different synonym handling strategies. Example:

   > ipod, i-pod, i pod

4. Multiple synonym mapping entries are merged. Example:

   > foo => foo bar
   > foo => baz
   > is equivalent to
   > foo => foo bar, baz

WARNING: This API is experimental and might change in incompatible ways in the next release.
