Okay, we need to take a step back and think about what you are trying to do.
Reading back in the thread and looking at your schema, you have a non-tokenized
field whose terms can include whitespace. There is in fact no good way to use
that with dismax, dismax doesn't work that way. What you can do as Yonik
suggests is use the 'field' query parser instead. You can force the use of the
'field' query parser with 'local params', or you can even create a combined
query with uses 'field' for one clause and 'dismax' for another, with nested
query syntax.
But every individual part of your query can only use one query parser at a
time, there's no way to use both at once.
But if you want to use that request handler, but force it to use 'field'
_instead_, that can be easily done:
&q=multi word query&defType=field&v=field_name
You don't even need 'local params', although you can also do it with 'local
params': &q={!field v=field_name}
That's it. (except all those values need to be URI encoded). But it won't be
using dismax anymore, although it'll be using that request handler you have set
up to default to dismax, you're telling it to use 'field' this time anyway.
If that doesn't do what you want, why don't you take a step back and tell us
what query behavior you are actually trying to create, and maybe someone can
give you some ideas for accomplishing it.

I've looked at solr local params. However, I can't figure out how to
integrate it with my full text search using dismax handler. Here is my full
text search request handler.
<requestHandler name="mb_listings" class="solr.SearchHandler">
<lst name="defaults">
<str name="echoParams">explicit</str>
<int name="rows">20</int>
<str name="defType">dismax</str>
<str name="qf">name_ngram^20 name^40 postal_code address description
long_description location keyphrase short_description category telephone
email website</str>
<str name="pf">name_ngram</str>
<str name="bf">fap^10</str>
<str name="fl">uuid</str>
<str name="version">2.2</str>
<str name="indent">on</str>
<str name="tie">0.1</str>
</lst>
<lst name="appends">
<str name="fq">type:Listing</str>
</lst>
<lst name="invariants">
<str name="facet">false</str>
</lst>
<arr name="last-components">
<str>spellcheck</str>
<str>elevateListings</str>
</arr>
</requestHandler>
Note: postal_code, keyphrase, category, telephone, email, website has field
type "text_keyword".
Thanks
