Provide an 'online' value to the Search Result Mustache template. This will, for example, allow you to put things in your Search Result template that will show up when your site is displayed live (PHP), but will not be output when your site is displayed using the offline Javascript, and vice versa.
eg.
{{#online}}
This will only display in your template if it's online.
{{/online}}
{{^online}}
This will only display in your template it it's offline.
{{/online}}
If the search UI is using typeahead and the user selects a suggested option to go right to a page, then a search is never logged as a search query; it's like the search never happened. Add a fetch request to log the search query just before sending the user on their way to the page.
Make 's_show_orphans' a runtime variable and normalize the SQL queries it's used in.
Also change generic '$select' variable to more semantic '$crawldata'.
Get rid of "avg_results" value; it's not intuitive. Instead make sure to use the results tally from the last recorded search query.
Use mb_strlen and mb_substr to avoid searching for single, but multibyte characters like bullet (•).
Using INSTR was correctly matching searches for 'ae' to the ligature æ, but was not matching searches for plain 'a' to å. However, using LIKE behaves exactly the opposite of this. Unless there is a better solution, use both INSTR and LIKE to create the query so all bases are covered.
Automatically encode/decode json when saving/reading ODATA config values.
Remove 'sp_links_crawled' config table value, now stored in 'sp_progress'.
Update Crawl Information window in real-time while crawler is running. Be more aggressive at reloading the page to get the latest data once a crawl has finished.
Time the setting of certain config values while crawling in a more sensible way.
Allow downloading of the page index as a csv.
Remove unnecessary database columns url_base and status_noindex
Store list of domains at crawl so we don't need to request them every page-load; you will need to reinstall fresh because of this change
Disable Query log download button if query log is empty.
Further database error resiliency.
Add many more punctuation normalization characters; normalize on search as well as storage.
Add count of MIME-types in Search Management UI.
Keep Page Index pagination page within limits; add UTF-8 BOM to CSV and TXT download output; use utf8mb4_unicode_520_ci collation to remove need for SQL REGEXP; add more latin accent equivalent characters.
