If you have multi-word synonyms you could use -
tokenizerFactory="solr.KeywordTokenizerFactory" - in the
SynonymFilterFactory filter factory declaration. This assumes that
your tokenizer for that field allows for keeping the phrases as a
single token (achieved by using solr.KeywordTokenizerFactory instead
of Standard Tokenizer), if it is not then you might miss the synonym
setting altogether. See the configuration below
<analyzer>
<tokenizer class="solr.KeywordTokenizerFactory"/>
<filter class="solr.TrimFilterFactory" />
<filter class="solr.StopFilterFactory" ignoreCase="true"
words="stopwords.txt" enablePositionIncrements="true"/>
<filter class="solr.SynonymFilterFactory"
tokenizerFactory="solr.KeywordTokenizerFactory"
synonyms="synonyms.txt" ignoreCase="true" expand="false" />
<filter class="solr.RemoveDuplicatesTokenFilterFactory"/>
</analyzer>
Then you can use synonyms like
Barack Obama,Barak Obama,Barack H. Obama,Barack Hussein Obama, Barak
Hussein Obama => Barack Obama
