Lucene allows for advanced search queries to be entered using keywords or symbols. Some examples are below:
Note that keywords must be in upper case.
Search Term | Result |
|---|---|
a4 AND paper | returns products containing the word "a4" and the word "paper" |
a4 OR paper | returns products containing the word "a4" or the word "paper" |
paper NOT a5 | returns products containing the word "paper" but not the word "a5" |
paper AND (a4 OR a5) | return products containing the word "paper" and either "a4" or "a5" |
"a4 paper" | returns products containing the string "a4 paper" (i.e the word paper must follows a4) |
title:a4 | returns products containing "a4" in the "title" field of the index |
Note that "+" can be used instead of "AND" and "-" can be used instead of "NOT". The below are equivalent to the above first 4 queries
- +a4 +paper
- a4 paper
- paper -a5
- +paper +(a4 a5)

Search Queries in CSS
In CSS, we assume that when users enter a number of words, they want an "and" search to be performed.
...
Any search containing ", +, -, NOT, OR, AND is passed directly to Lucene.
