Accuracy suffix/prefix options

This is feature request.

My case is simple: I perform search on prefixes of words in the index and so I would like to highlight only matches which are prefixes (not in the middle of word). Example:

query: “fix” text: “fix fixes prefix” result: “fix fixes prefix” “fix” in “prefix” is not highlighted because it is not prefix of “prefix” 😉

Solution: it is enough to support new value of ‘accuracy’ configuration option (I called it ‘prefix’) and support it with addition of following code to ‘createAccuracyRegExp(str)’ function:

    case "prefix":
        return "(^|\\s" + lsJoin + ")(" + str + ")";

@julmot What you describe is exactly my use case - I have full-text search results and I want to highlight all matching prefixes (and only prefixes) of all words in the text (not one per line/div etc.). Note that this is similar and agrees with existing accuracy options - same approach to words, only matching logic is different:

• “exact” - matches only exactly same words,
• “partially” - matches any part of any word,
• “prefix” - matches only prefixes of words. If one “would expect one ‘Lorem’ match per line (div)”, then it would be completely different logic - but this is not the case!

@patrickf3139 I have my changes in local repository. If you are interested, I will fork the project and apply my changes.
