solr search with keywords having space not giving proper results

I have list of keywords few of them are below

Cheap hotels Dubai hotel extended hotel .... ..

I have store(storeName:HotelsStore) for this and added the keywords above(which have white space) to my store and doing solr indexing. If we search with "Cheap hotels" my store:HotelsStore is not showing reults.

But If I add "Cheaphotels" without space and indexing. If I search with "Cheaphotels" then my desired store(HotelsStore) is showing in results.

Note: We are using lucene 5.4 and solr 5.4.

Please help me on this.

Thanks, Syamala.

Try to generate word parts using WordDelimiterFilter filter on storeName field.

You could customise this filter how you want.

Just example:

One way of doing so is to specify generateWordParts="1" catenateWords="1" in the analyzer used for indexing, and generateWordParts="1" in the analyzer used for querying. Given that the current StandardTokenizer immediately removes many intra-word delimiters, it is recommended that this filter be used after a tokenizer that leaves them in place (such as WhitespaceTokenizer).

<tokenizer class="solr.WhitespaceTokenizerFactory"/>
      <filter class="solr.WordDelimiterFilterFactory"
            generateWordParts="1"
            generateNumberParts="1"
            catenateWords="1"
            catenateNumbers="1"
            catenateAll="0"
            preserveOriginal="1"
            />

GENERATE_WORD_PARTS set to 1

Causes parts of words to be generated:

"HotelsStore" => "Hotel" "Store"
