Let Lucene include spaces in term for exact match

Question

I want my Lucene query to contain something similar to:

companyNam:mercedes trucks

Where it will do an exact match for the string "mercedes trucks" in the companyName field.
The companyName is an untokenized field, but anything with a space returns null results..

new TermQuery(new Term("companyName", "mercedes trucks"));

Always results 0 results if there is a space involved. Otherwise my program is working fine.

Answer 1

Maybe replace:

mercedes trucks 

with

mercedes?trucks

Works for me.

Answer 2

Use a PhraseQuery like this:

//create the query objects
BooleanQuery query = new BooleanQuery();
PhraseQuery q2 = new PhraseQuery();
//grab the search terms from the query string
string[] str = Sitecore.Context.Request.QueryString[BRAND_TERM].Split(' ');
//build the query
foreach(string word in str)
{
  //brand is the field I'm searching in
  q2.Add(new Term("brand", word.ToLower()));
}

//finally, add it to the BooleanQuery object
query.Add(q2, BooleanClause.Occur.MUST);

//Don't forget to run the query
Hits hits = searcher.Search(query);

Hope this helps!
