** Summary **

details about searching this wiki

** Description **

   http://wiki.tcl.tk/_/search:   the search page for this wiki.  It corresponds to the ''search in titles'' box in the left column, and is based on [sqlite]'s [http://www.sqlite.org/fts3.html%|%full text search]. The search string is passed as `MATCH` argument, including the `*` characters. Check [http://www.sqlite.org/fts3.html%|%www.sqlite.org/fts3.html] for more information about [sqlite] and full text search.

   [Search]:   A page with additional details about the search facilities
   [http://www.google.com/search?q=site%3Awiki.tcl.tk%|%Google search of this site]:   just add your search terms after the google search term '''site:wiki.tcl.tk'''
   URL word search:   One way to search for for a word in page titles is by adding the word to the end of [http://wiki.tcl.tk/%|%this URL].  For example, http://wiki.tcl.tk/calling shows a list of pages containing the word, "calling" in the title.  However, if there is an exact title match, then that page is returned rather than a list of search results.  For example, http://wiki.tcl.tk/time returns the [Time] page directly.
   URL Wildcard search:   can also be perf rme by typing a certain URL.   For example, http://wiki.tcl.tk/*time returns the results of a title search followed by the results of a full-text search of page content.


The `*` used in previous versions of the search to distinguish between
searching in titles or page content is no longer supported.  Searches are now
always done on titles and page content.  The results are listed sorted on the
last-edited-data, most recent first.  Results are presented in two groups, tile
results are shown in the first group, followed by the results of full-page
content search in the second group.

The [sqlite] in use at the wiki has been compiled with
`-DSQLITE_ENABLE_FTS3_PARENTHESIS` so the ''Enhanced Query Syntax'' is
available. This makes is possible to do the searches with an implicit `AND` as
before but also allows you to refine your search using the `AND`, `OR` and
`NOT` keywords.

[jnc]: Using the FTS3 Parenthesis option, you can now search for things such as
"https NOT soap" or "https AND (soap OR json)"

[tjk]: If you want to search for an explicit string such as "package require registry" you should connect the words with a NEAR/2 qualifier. Thus a search for 'package NEAR/2 require NEAR/2 registry' will find all pages that contain the string "package require registry".

[emj]: Actually you can just search for "package require registry" '''including''' the quotes in the search box.

[EMJ]: You don't need to search for pages in a category since the category page itself will give you that, but you can search for a page that is in ''two'' categories with

 categor* NEAR cat1 NEAR "other cat"

(quote any category name with more than one word). This will work for both older and newer category markup but will miss if a page has too many categories (but you could try NEAR/20 for that). It will also miss a single category link in the middle of the page with the other at the end, but there may be other tricks to cover that (which may become too complicated to be viable).
