SOLR phrase query

I have a slight problem when searching with SOLR 4.0 and attempting a phrase query.

I have a field called "idx_text_general_ci" which is a case insensitive (all lowercased) field made up of all fields.

When I try and search for a phrase (marine fitter) my SOLR refuses to search for the phrase instead splitting the phrase into 2 words - 

/select?defType=edismax&q=idx_text_general_ci:marine%20fitter&debugQuery=true

debugQuery=true output below:

<lst name="debug">
<str name="rawquerystring">idx_text_general_ci:marine fitter</str>
<str name="querystring">idx_text_general_ci:marine fitter</str>
<str name="parsedquery">
(+(idx_text_general_ci:marine DisjunctionMaxQuery((id:fitter))))/no_coord
</str>
<str name="parsedquery_toString">+(idx_text_general_ci:marine (id:fitter))</str>

As you can see above it splits the query into 2 parts (idx_text_general_ci:marine then id:fitter).

THe problem I have is that I have an exact match for "marine fitter" that appears twice in the idx_text_general_ci field yet it's ranked with a lesser score than a document with the word "marine" appearing 3 times. I know this will not be the case if my SOLR was to search the field with the phrase as expected.

If I wrap the phrase in quotes I get zero results.

Any help or a nudge in the right direction would be much appreciated.

Thanks in advance

What's happening here is that your default query field appears to be id, and because you're specifying your query as 

idx_text_general_ci:marine fitter

it gets translated in Solr as a DisjunctionMaxQuery for idx_text_general_ci:marine and id:fitter. Presumably, you want idx_text_general_ci:marine and idx_text_general_ci:fitter. You have two options: 1) you can prefix each word with the correct field followed by a colon, or you can change the defaultSearchField in schema.xml to be idx_text_general_ci.

I'm baffled as to why you get zero results when you wrap it in double quotes though. But doing the above should help you.
