Hi all I implemented an autocomplete functionality, which is pretty classical: a user types in some words in an input field, and sees a list of matches in a drop-down.
I've done it using filters (BooleanFilter, and TermsFilter + PrefixFilter), and it's working against and index (loaded in RAM) with 3+ mio documents with avg. time of 150-300 ms. The resulting filter instance looks like: termsFilter + termsFilter + prefixFilter (the right part is left *open*) Now I wanna try optimizing the whole thing by providing a possibility of incremental search with the caching of a previous filter's results with CachingWrapperFilter. AFAIK, you cannot modify a CWF, once it's filled. How a following scenario can be implemented? - a user types 'aaa bbb' in, then adds 'ccc'. How to cache results of 'aaa bbb' and the apply 'ccc'-filter to it and cache the new filter again?
