During the search operation process, we found that users do not know what to search and how to search when encountering problems. therefore, recommendation of topics of interest and popular keywords for users becomes a detail that must be paid attention to in daily operations. vertical and horizontal search can further explore and refine Forum information, it is concluded that hotspot keywords are recommended to users in different forms in various situations, so that users can stay on your site for a while. At the same time, the community value is displayed on the search results page in the best and most relevant form!

3. Sphinx full-text search settings

Generally, Sphinx is an independent search engine designed to provide other applications with full-text search functions featuring high speed, low space usage, and high result relevance.
1. set the Sphinx host name or Sphinx service socket address
After enabling Sphinx full-text search, enter the Sphinx host name. for example, enter "localhost" for the local host or enter the Sphinx service socket address, which must be an absolute address:
For example,/tmp/sphexample. sock.
2. set the sphsf-host Port
Enter the sphsf-host port, for example, 3312. if the host name is set to the socket address, you do not need to set it here.
3. set the title Index Name
Enter the title primary index name and the title incremental index name in the Sphinx configuration, for example, "threads, threads_mintue ".
Note: Multiple indexes are connected with the English symbol "," and must be filled in according to the index name in the sphsf-configuration file.
4. set the full-text index name
Enter the full-text primary index name and full-text incremental index name in the Sphinx configuration, for example, "posts, posts_mintue ".
5. set the maximum search time
Enter the maximum search time, in milliseconds. The parameter must be a non-negative integer. The default value is 0, meaning no limit.
6. set the maximum number of matched items returned
Enter the maximum number of matched items returned. it must be a non-negative integer. the default value is 10000.
7. set full-text index scoring mode

Three modes are available:
1) SPH_RANK_PROXIMITY_BM25, default mode. Both the phrase score and BM25 score are used and combined.
2) SPH_RANK_BM25: statistical relevance calculation mode. only BM25 is used for scoring (the same as most full-text search engines ). This mode is fast, but may degrade the quality of the query results containing multiple words.
3) SPH_RANK_NONE: disable the scoring mode. this is the fastest mode. In fact, this mode is the same as Boolean search. All matching items are assigned a weight of 1.
