Just escape the special characters of the URL with backslash or put the
entire URL in quotes. The slash is particularly problematic since it
introduces a regular expression. Dismax has a less-sophisticated syntax and
automatically escapes more special characters.

Subject: Edismax vs Dismax
Hi, the application I am working on switched to edismax parser and I found
some weird behavior.
I have this field:
<fieldType name="url" class="solr.TextField" omitNorms="false">
<analyzer type="index">
<tokenizer class="solr.PatternTokenizerFactory" pattern="\b" />
<filter class="solr.StopFilterFactory" words="url_stopwords.txt"
ignoreCase="true"/>
<filter class="solr.EdgeNGramFilterFactory" minGramSize="1"
maxGramSize="20" />
<filter class="solr.LowerCaseFilterFactory" />
</analyzer>
<analyzer type="query">
<tokenizer class="solr.PatternTokenizerFactory" pattern="\b" />
<filter class="solr.StopFilterFactory" words="url_stopwords.txt"
ignoreCase="true"/>
<filter class="solr.LowerCaseFilterFactory" />
</analyzer>
</fieldType>
The string that is indexed is: facebook.com/profile.php?id=123456789
When I do use the dismax parser the query returns one result and 0 with
edismax. Here are the queries I tried:
1 result:
fq=type%3ASite&sort=score+desc&q=facebook.com%2Fprofile.php%3Fid%3D1571031169&fl=%2A+score&qf=url_url&defType=dismax&mm=1&start=0&rows=20&
0 results:
fq=type%3ASite&sort=score+desc&q=facebook.com%2Fprofile.php%3Fid%3D1571031169&fl=%2A+score&qf=url_url&defType=edismax&mm=1&start=0&rows=20&
Can someone please help me figure this out?
Thank you,
Alex
