/**
* Create a field query from the input value, applying text analysis and constructing a phrase query if appropriate.
*
Other parameters: f, the field
*
Example: {!field f=myfield}Foo Bar creates a phrase query with "foo" followed by "bar"
* if the analyzer for myfield is a text field with an analyzer that splits on whitespace and lowercases terms.
* This is generally equivalent to the Lucene query parser expression myfield:"Foo Bar"
