| − | + | # Different indexes are created for the entire contents of the wiki. Each index is weighted differently. So, for example, "Lead-in" text is the wikitext between the top of the page and the first heading. Words found here are deemed more relevant to a users search query than the same word if found in the body text of an article. So, in this wiki, [{{fullurl:Special:Search|search=yaml|fulltext=Search}} searching for the word "YAML"] puts the [[Ansible]] article ahead of the [[Eclipse]] article in search results. | |
| − | + | # Content as well as all files uploaded into the system are indexed. For example, [{{fullurl:Special:Search|search=fai|fulltext=Search|profile=all}} a search for "FAI"] lists both the [[Cloning]] article as well as the [[:File:Fai poster a4.pdf|PDF file]] And the file is not listed only because of the file name, but also because of the (indexed) file content. [{{fullurl:Special:Search|search=ed%20roman|fulltext=Search|profile=all}} A search for "Ed Roman"] will bring up the Enterprise Java Beans Design Patterns PDF file ([{{fullurl:File:Ejbdesignpatterns.pdf|page=13}} see p. 13 where Ed Roman is mentioned].) | |
