Implement research that searches for keyphrase or keyphrase/synonyms words

[nataliashitova]

We need to implement research that searches for keyphrase word forms only or for keyphrase and for synonyms word forms within a text string.

The research should input a topicForms structure from the paper and the text string.
The research should output

• a boolean that shows if the keyphrase or synonym was found in the string
• a string "all", "some", "one" or "none" to code how many of the content words from the keyphrase were found in the string (see Implement research that checks if keyphrase/synonym word forms are present in the string. #1634 )
