+By default OpenSubsonic servers **must accomodate** the following rules for `query` parameters:
+
+* Search only by `name`/`title` for the object type
+* Prefix match (starts with) by default for all search terms
+* Split all words by space (` `) into individual (**OR**) search terms
+* Wrap multiple words with quotes (`"`) to group them together
+* Join multiple words with plus (`+`) to group them together
+* Group search terms are **EXACT** matched by default
+* Group search terms ending with `*`|`%` are prefix matched (**LIKE**)
+* Special characters (`*`|`%`) inside group strings are literal
