I constructed something like this in my master degree. What I bascially did was to write a custom analyzer. However I identified the top 100 most searched phrases in my collection, and then filtered for those. If a document contained a identified phrase, then the analyzer would construct a Token for those terms. Another approach is to decide that only two-word phrases should be search for. And, for instance, find verbs and use the "word right after". Example string: "The boat was very fast". Tokens: "The boat", "was", "very fast". If your analyzer contain a range of phrases to search for, then it should be straightforward to identify those phrases and index them as Tokens. Just remember to set the start and end offset of the Token to correct values.
