search query bug

[Denis de Bernardy]

I was working on the wordpress search query, when i bumped into this amusing bug:

e.g. with the following text:

[some text][markdown url id]

[markdown url id]: /some_page/

You get the following false positives:

$s = 'markdown url id'
$s = 'some_page'

i submitted the bug to michel fortin already.

On second inspection, it has more to do with WordPress than with Markdown.

The following bug is more interesting:

WordPress searches in tags, links, etc. whereas it would be more relevant to search in a plain text, cleaned up version of the text.

Suggested workaround 1:

• apply-filters to text upon saving
• store in new field wp_posts.search_text
• conduct searches in search_text rather than in post_content

side effects:

• this requires reindexing from time to time when plugins are installed or removed -- are there any on_plugin_enable and on_plugin_disable handles?

Suggestion workaround 2:

• apply filters to search result contents to verify its relevance

side effects:

• very slow
