String searching algorithms in Java

Question

I am doing string matching with big amount of data.

EDIT: I am matching words contained in a big list with some ontology text files. I take each file from ontology,

Answer 1

Why don't you use the indexOf method in java. As per the availability of memory, read the content. Do an indexOf and get all the lines you need. Load the next set of contents.

If reading from file use nio streams.

May be the idea is bad, But I belive in java. It will use the best algorithm.

Better if you use regular expression.
