-------------------------------------
Summary: After Solr 5.5, mm parameter doesn't work properly
Key: SOLR-9174
URL: https://issues.apache.org/jira/browse/SOLR-9174
Project: Solr
Issue Type: Bug
Components: query parsers, search
Affects Versions: 6.0.1, 6.0, 5.5
Reporter: Issei Nishigata
“mm" parameter does not work properly, when I set "q.op=AND” after Solr 5.5.
In Solr 5.4, mm parameter works expectedly with the following setting.
---
[schema]
<fieldType name="bi_gram" class="solr.TextField">
<analyzer>
<tokenizer class="solr.NGramTokenizerFactory" minGramSize="2"
maxGramSize="2"/>
</analyzer>
</fieldType>
[request]
http://localhost:8983/solr/collection1/select?defType=edismax&q.op=AND&mm=2&q=solar

After Solr 5.5, the result will not be the same as Solr 5.4.
Has the setting of mm parameter specs, or description of file setting changed?

[Solr 6.0.1]

<str name="q">solar</str>
<str name="defType">edismax</str>
<str name="q.op">AND</str>

<str name="parsedquery">

</str>
<str name="parsedquery_toString">+((+text:so +text:ol +text:la
+text:ar))</str>
...
As shown above, parsedquery also differs from Solr 5.4 and Solr 6.0.1(after
Solr 5.5).
