Supports v14.0+

Usage

Search strings, files or wikipedia articles for a lexical pattern.

oospPattern = BoundToken[WordToken[2], BoundToken["specie"|"species"]];

oospResults = LexicalCases[oosp, oospPattern]

All Text Content Types can be used, however, some will take unreasonably long to expand, especially if it's meant to represent a hefty piece of text, like a topic type. The basic parts of speech types are good ones to start with:

alice = ExampleData[{"Text", "AliceInWonderland"}];
alicePattern = "Alice" ~~ TypeToken["Verb"] ~~ TypeToken["Adverb"];

aliceResults = LexicalCases[alice, alicePattern]

---

Use lexical patterns in StringCases, StringPosition and StringmatchQ by wrapping the pattern with LexicalPattern.

Here's an example creating an operator of StringCases:

aliceOp = StringCases[LexicalPattern["Alice" ~~ TypeToken["Verb"] ~~ TypeToken["Adverb"]]];
