Some of the most popular and useful queries are run regularly and can be found at Wikipedia:Database reports. If neither of these suits your query, you can request that someone run a query for you, or download your own copy of the database to work on.
A search link stores a query in a link that takes you to live search results for that stored search. They're found on user pages and talk pages. They're found on user pages and talk pages. Use one to bring the full feature set of MediaWiki Search, or features of external search engines, to bear on users unfamiliar with their search parameters.
Database reports query MediaWiki in search of patterns. Their output helps users by providing them with utility reports, used by community members to improve the encyclopedia (e.g., Untagged stubs ( configuration )) and statistical reports, which have past and present informational value (e.g., Page count by namespace ( configuration )).
For each link the page in which it is found is listed, along with the exact target URL of the link on that page. The results are ordered alphabetically by target URL. (For very large or specialized external link searches, one may also use SQL queries against the externallinks table at Quarry .)
Examples of data that would lead to a query: a male patient being on female birth control medication or having had an abortion, or a 15-year-old participant having had hip replacement surgery. Each query has to be resolved by the individual attention of a member of each local research team, as well as an individual in the study administration.
If you need to make changes to a number of articles based on a particular query, you can post to the bot requests page, depending on how many changes are needed. For long-term review and checking, database reports are available. Quarry does not have access to page content, so queries which require checking wikitext cannot be answered with Quarry.
A wikilink (or internal link) is a link from one page to another page within the English Wikipedia, or, more generally, within the same Wikipedia (e.g. within the French Wikipedia), in other words: within the same domain, or, even more generally, within the same Wikimedia project (e.g. within Wiktionary).
If a query scans millions of rows, consider breaking it into multiple queries. Query time versus number of rows increases exponentially, not linearly. Indexes - Check the documentation on MediaWiki wiki for each database table. There is a list of indexes. Pay attention to what those are, since you'll want to try to search only those fields.
