Solr wildcard query with whitespace

Question

I have a wildcard query that looks something like:

I\'d like it to match \"los angeles\" and \"los altos\". A query like

Answer 1

I had the same problem in my project. When ever I was search for a word along with the whitespace I was not geting the result. So I replaced the whitespace with a hyphen "-" while indexing and querying. Below is the schema.xml snipet which I used to do so:

<fieldType name="text_ci" class="solr.TextField" positionIncrementGap="100">
<analyzer type="index">
<tokenizer class="solr.NGramTokenizerFactory" minGramSize="2" maxGramSize="250"/>
<filter class="solr.LowerCaseFilterFactory"/>
  <filter class="solr.TrimFilterFactory" />
    <filter class="solr.PatternReplaceFilterFactory"
            pattern="([/\s+])" replacement="-" replace="all"
    />
</analyzer>
<analyzer type="query">
<tokenizer class="solr.EdgeNGramTokenizerFactory" minGramSize="2" maxGramSize="250"/>
<filter class="solr.LowerCaseFilterFactory"/>
 <filter class="solr.TrimFilterFactory" />
    <filter class="solr.PatternReplaceFilterFactory"
            pattern="([/\s+])" replacement="-" replace="all"
    />
</analyzer>
</fieldType>

Answer 2

Might I suggest the solr prefix query plugin if you are only using it for wildcards on the suffix as we were http://lucene.apache.org/solr/4_0_0/solr-core/org/apache/solr/search/PrefixQParserPlugin.html

example usage

http://localhost:8983/solr/collection/select?q={!prefix%20f=name}Bob%20Smi

would match "Bob Smith" or "Bob Smit" but not convert into a check of ("Bob" OR "Smi*") as would happen if you used the first solution you might consider along the lines of q=name:Bob%20Smi*

Hopefully this is of some help to you or someone else looking for a simple solution because I was banging my head against a wall for hours before I found this!

Answer 3

For me worked

<fieldtype name="text_like" class="solr.TextField">
    <analyzer type="index">
        <tokenizer class="solr.NGramTokenizerFactory" minGramSize="3" maxGramSize="1000"/>
        <filter class="solr.LowerCaseFilterFactory"/>
    </analyzer>
    <analyzer type="query">
        <tokenizer class="solr.LowerCaseTokenizerFactory"/>
    </analyzer>
</fieldtype>

and query field:*some\ phrase* (in java literal one needs to escape \ as \\).
