How do I federate an index query? So given the query filter age=18 process is to find 18 from the term index in the general position of dictionary, and then from the term dictionary to find exactly 18 of terms, and then get a posting A list or a pointer to the posting list position. Then the process of querying gender= women is similar. Finally, age=18 and gender= woman is the two posting list to do a "and" merge .This theoretical "and" merging operation is not easy.
