Elizabeth Haubert commented on SOLR-12243: ------------------------------------------ Current expansions looks perfect, thank you Steve. Observation with the current approach is that the combinatorics for larger queries and/or longer expansions could get hefty. Would it be worth adding a note about this in the edismax documentation around pf/pf2/pf3. Similar to the note around aliasing and qf [in the ref guide|https://lucene.apache.org/solr/guide/7_3/the-extended-dismax-query-parser.html#field-aliasing-using-per-field-qf-overrides]: Multi-term synonyms with pf When a phrase query specified with PF/PF2/PF3 contains a synonym expansion, then a separate pf clause will be generated for each permutation of each synonym. For example, in a system with synonyms for dog, canine and cat,feline the query "dog chased cat" would generate the following pf clauses: * dog chased cat * canine chased cat * dog chased feline * canine chased feline > Edismax missing phrase queries when phrases contain multiterm synonyms > ---------------------------------------------------------------------- > > Key: SOLR-12243 > URL: https://issues.apache.org/jira/browse/SOLR-12243 > Project: Solr > Issue Type: Bug > Security Level: Public(Default Security Level.
