A very general search tool, returning all matrices whose metadata, in ANY column, is matched by the query string.

1 2	## S4 method for signature 'MotifList' query(object, andStrings, orStrings, notStrings, ignore.case=TRUE)

`object`	a `MotifList` object.
`andStrings`	a `character` string vector, length one or more, every element of which must be found in the metadata
`orStrings`	a `character` string vector, length one or more, any element of which must be found in the metadata
`notStrings`	a `character` string vector, length one or more, none of which may appear in the metadata
`ignore.case`	a `logical` value, default TRUE
