# search operator for features

[codykingham]

I second the need for a != operator in TF search.

There are now new possibilities:

• nodetype feature : feature is present and not None
• nodetype feature! : feature is not present or None
• nodetype feature>val : feature has value greater than val (numerical features only)
• nodetype feature<val : feature has value less than val (numerical features only)
• nodetype feature~regexp : feature matches regular expression (string features only)

So: word vt=infc lex~(?!^>MR[)

Actually, this was an embarrasingly good suggestion. Regular expressions are nice, but clumsy when you just want to use them for the non-equality of values. So I have implemented the # after all. And saying word vt# means: feature vt has no value for word.

It will be included in the next release.

Excellent, thanks!
