Search Syntax Using Edismax And

This follows a simple phrase based search process with full keyword OR and AND support.

Search Features

Use + or - to denote mandatory or prohibited matches of a given phrase.
Use quotes to group phrases for more precise matching, such as "word1 word2".
Searches are case-insensitive such that upper and lower case letters are treated as indistinguishable, except for AND, OR, and NOT special use words.
Each space separated word or phrase is automatically combined using an AND condition except when the following word or phrase does not have a leading + or - or when OR is explicitly specified between words.
Explicitly add either the word AND (all upper-case) or the word OR (all upper-case) between each space separated word to override the default combining condition.
Explicitly add NOT (all upper-case) to exclude a word or phrase just like the - character.
Trailing punctuation is generally ignored when matching and can be omitted (for example, Center, and Center should be treated as the same search).
