full-text-search

I have a text file of size 115MB. It consists of about 20 million words. I have to use the file as a word collection, and use it to search the occurrence of each user-given words from the collection. I am using this process as a small part in my project. I need a method for finding out the number of occurrence of given words in a faster and correct manner since i may use it in iterations. I am in need of suggestion about any API that i can make use or some other way that performs the task in a quicker manner. Any recommendations are appreciated.
