I know that .index() will return where a substring is located in python. However, what I want is to find where a substring is located for the nth time, which would work like this: >> s = 'abcdefacbdea' >> s.index('a') 0 >> s.nindex('a', 1) 6 >>s.nindex('a', 2) 11 Is there a way to do this in python? ...

I am trying to search for long, approximate substrings in a large database. For example, a query could be a 1000 character substring that could differ from the match by a Levenshtein distance of several hundred edits. I have heard that indexed q-grams could do this, but I don't know the implementation details. I have also heard that L...
I know there are already several similar questions here, but I need some recommendations for my case (couldn't find anything similar).

The haystack doesn't change, so I can bear with large precomputati...

Taking substrings of a string is a very common string manipulation operation, but I heard that there might be considerable differences in performance/implementation between the Java and .NET platform. Specifically I heard that in Java, java.lang.String offers constant time operation for substring, but in .NET, System.String offers linear...
