Hi,all ADJ matches if the words appear in the same order as in the query. Now I focus on the performance. Test case 2 * T7200 at 2.00GHz 3.0GB Xapian:1.2.5 About 2.3GB of database files and 250,000 documents. When I use ADJ mode just like "how ADJ/1 much", It cost about 15s. So my question is how to improve performance. Thanks.
