Visitors type into the search box and get nothing, an error line, or results that look wrong. Work through the causes below in order; the first three cover most cases.
Version 2.0 and later search products, blog posts, events and services without any other app. Regular pages and forum posts still come only from the index that the Wix Site Search app (free, by Wix) keeps for your site. Earlier versions (1.x) read only that index; without it there is nothing to search.
Connected with an "Unavailable: …" line under it means one or more types did not answer on that check; reload the page to check again. Error means the app itself could not be reached; try again in a minute.
The widget searches only the content types ticked in its settings panel. If products never show up, Products is probably unticked.
Products appear in results right away. New blog posts and pages usually show up within a minute of publishing. The app also keeps each answer for 60 seconds, so a search run just before publishing can repeat the old answer for up to a minute. On 2.0 without Wix Site Search, changes reach search when Wix reports them to the app, and the whole search copy is rebuilt once it is more than a day old.
The Wix index stores each page's title with its SEO description glued on the end. Since version 1.22.0 the app cuts that tail off again: when a title ends with the first 12 or more characters of the description, the overlap is removed and the description shows as the snippet instead. Updates reach your site automatically; nothing to reinstall. If you still see a glued title, send the page address to support.
The app answered with an error, the request failed, or every content type timed out (each index call gets 4 seconds). It usually clears on the next try; if it stays, check the Setup badge as in step 1.
Most content types answered but one did not. The results shown are correct; search again in a minute for the rest.
The site went over its search budget. Identical searches are served from a 60-second cache and do not count; fresh searches do, up to 600 per site per minute, with a smaller per-caller budget on the public route. Normal visitors do not reach this; a script does.
The app has not registered this site. Open Apps → Site Search Bar in the dashboard once, then reload the live page.
The request worked and nothing matched. Check steps 2 and 3, then try a shorter word.
When a Korean query returns nothing, the app looks for the closest term among nearby titles and searches for that instead; the panel then says "Showing results for: …" with the corrected word. This runs only for queries containing Hangul. For other languages the index's own fuzzy matching still catches small misspellings ("abstrat" still returns matches), but no correction hint appears.
These are Pro features. On the Free plan you can still save synonyms and rules in the dashboard, but searches ignore them until the site is on Pro (a running free trial counts as Pro). After an upgrade the change reaches searches within a couple of minutes.
On Pro, if a rule still seems ignored:
Email beobjoong@gmail.com with your site address, the word you searched for and the line shown under the box. A screenshot of the Setup card in the app dashboard helps.
