I wonder if you could accomplish your goal by creating another field
during indexing which holds the number of terms in the "species" field.
If that's possible, then you might get what you want with a query like:
+species:"homo sapien" +num_species:1.

Could some more experienced users suggest a solution to my problem. I
have documents which contain multiple terms and phrases, and I wish to
collect documents which match only the term I query for.
For example:
Doc1 contains,
species:"homo sapien" Mammalia
Doc2 contains,
species:"homo sapien"
I wish to collect documents ONLY with "homo sapien" but a search for
species:"homo sapien" returns both documents as they both contain the
phrase.
I have written code to cache every term for every field an I hoped
that I could do the search - species:"homo sapien" -species:Mammalia.
Unfortunately the terms homo and sapien seem to be separate. So when
I collect every term to use with the "-" operator I end up with a
query thus
species:"homo sapien" -species:(homo Mammalia sapien)
which isn't the same.
Can anybody suggest another approach?
Many thanks
Iain
