Alexandr created SOLR-11954:
-------------------------------
Summary: Search behavior depends on kind of synonym mappings
Key: SOLR-11954
URL: https://issues.apache.org/jira/browse/SOLR-11954
Project: Solr
Issue Type: Bug
Security Level: Public (Default Security Level. Issues are Public)
Affects Versions: 7.2.1
Reporter: Alexandr
For field with such type
{noformat}
<fieldtype name="fulltext_en" class="solr.TextField"
autoGeneratePhraseQueries="true">
<analyzer type="index">
<tokenizer class="solr.WhitespaceTokenizerFactory"/>
<filter class="solr.WordDelimiterGraphFilterFactory"
generateWordParts="1" generateNumberParts="1" splitOnNumerics="1"
catenateWords="1" catenateNumbers="1" catenateAll="0" preserveOriginal="1"
protected="protwords_en.txt"/>
<filter class="solr.FlattenGraphFilterFactory"/>
</analyzer>
<analyzer type="query">
<tokenizer class="solr.WhitespaceTokenizerFactory"/>
<filter class="solr.WordDelimiterGraphFilterFactory"
generateWordParts="1" generateNumberParts="1" splitOnNumerics="1"
catenateWords="0" catenateNumbers="0" catenateAll="0" preserveOriginal="1"

<filter class="solr.LowerCaseFilterFactory"/>
<filter class="solr.SynonymFilterFactory"
synonyms="synonyms_en.txt" ignoreCase="true" expand="true"/>
</analyzer>
</fieldtype>{noformat}
If synonyms configured in next way
{noformat}
b=>b,boron
2=>ii,2{noformat}
Then for query "my_field:b2" parsedQuery looks so "my_field:b2
Synonym(my_field:2 my_field:ii)"
But when synonyms configured in such way
{noformat}
b,boron
ii,2{noformat}
Then for query "my_field:b2" parsedQuery looks so "my_field:b2 my_field:\"b 2\"
my_field:\"b ii\" my_field:\"boron 2\" my_field:\"boron ii\")"
The second query is correct (it uses synonyms for two parts after word split).
Search behavior should not depends on kind of synonym mappings.
This issue also has been discussed in solr user mailing list
[http://lucene.472066.n3.nabble.com/SynonymGraphFilterFactory-with-WordDelimiterGraphFilterFactory-usage-td4373974.html]
It reproduced for me for Solr 7.1.0, but it also can be reproduced for 7.2.1
