This is a pretty rudimentary search engine.
Boolean operators OR, AND, AND NOT, and BUT NOT are allowed, as is grouping of search terms using parentheses.
The simplest search, aside from a single word search, would be a list of words. These words are then ORed together for the search.
Here are some examples of some valid searches:
- this OR that
- this BUT NOT that
- this that other
- (this AND that) BUT NOT other
- "phrase one" OR ("phrase two" AND "phrase three")
- ("this phrase" OR "that phrase") AND ("third phrase" OR "fourth phrase")
