If you have a field of type 'text_general', searching for:
q=good microwave
Will find any documents with either 'good' or 'microwave' in them.
Searching for:
q="good microwave"
will find any documents that contain both terms next to each other.
q="good microwave"^5 good microwave
will find any documents that contain either term, but will boost
documents that contain the terms next to each other above those that
don't.
Note also, when Lucene scores a document, it uses a 'co-ordination
factor' which takes into account the number of query terms that matched
your document. Thus, a document matching both terms will score more
highly than a document only matching one of them.
So, a part of the question is whether you wish to *only* show documents
that include both terms, or whether you are happy for good matches to be
prioritised.
