Search settings

Here you can define what search backend will be used for indexing posts and performing searches. You can set various options that can influence how much processing these actions require. Some of these settings are the same for all search engine backends.

General search settings

Enable search facilities: Enables user facing search functionality including member search.: Yes No

User search flood interval: Number of seconds users must wait between searches. This interval is checked independently for each user.: Seconds

Guest search flood interval: Number of seconds guests must wait between searches. If one guest searches all others have to wait until the time interval passed.: Seconds

Search page system load limit: If the 1 minute system load exceeds this value the search page will go offline, 1.0 equals ~100% utilisation of one processor. This only functions on UNIX based servers.

Min author name characters: Users have to enter at least this many characters of the name when performing a wildcard author search. If the author’s username is shorter than this number you can still search for the author’s posts by entering the complete username.

Maximum number of allowed keywords: Maximum number of words the user is able to search for. A value of 0 allows an unlimited number of words.

Default number of returned characters: The default number of characters that will be returned while searching. A value of 0 will return the entire post.

Search result cache length: Cached search results will expire after this time, in seconds. Set to 0 if you want to disable search cache.: Seconds

Search backend

Search backend: phpBB allows you to choose the backend that is used for searching text in post contents. By default the search will use phpBB’s own fulltext search.

phpBB Native Fulltext

Enable fulltext updating: Updating of fulltext indexes when posting, overridden if search is disabled.: Yes No

Min characters indexed by search: Words with at least this many characters will be indexed for searching.

Max characters indexed by search: Words with no more than this many characters will be indexed for searching.

Common word threshold: Words which are contained in a greater percentage of all posts will be regarded as common. Common words are ignored in search queries. Set to zero to disable. Only takes effect if there are more than 100 posts. If you want words that are currently regarded as common to be reconsidered you have to recreate the index.: %

Sphinx Fulltext Configure the following settings to generate sphinx config file

Path to data directory: It will be used to store the indexes and log files. You should create this directory outside the web accessible directories. (should have a trailing slash)

Sphinx search daemon host: Host on which the sphinx search daemon (searchd) listens. Leave empty to use the default localhost

Sphinx search daemon port: Port on which the sphinx search daemon (searchd) listens. Leave empty to use the default Sphinx API port 9312

Indexer memory limit: This number should at all times be lower than the RAM available on your machine. If you experience periodic performance problems this might be due to the indexer consuming too many resources. It might help to lower the amount of memory available to the indexer.: MiB

Sphinx config file: The generated content of the sphinx config file. This data needs to be pasted into the sphinx.conf which is used by sphinx search daemon. Replace the [dbuser] and [dbpassword] placeholders with your database credentials.: The sphinx data directory path is not defined. Please define the path and submit to generate the config file.
