not support index: %s

Error message

not support index: %s

What it means

search.Init(mode) looks the requested mode up in searcher.NewMap and it is not a registered searcher backend, so the configured index type string is rejected. Registered names come from the compiled-in searcher registry (database, meilisearch, ...; 'none' is handled earlier with a warning).

Solutions

1. Set the search mode to an exact registered value (check searcher.NewMap keys in your build, e.g. 'database', 'meilisearch', or 'none')
2. Remove surrounding whitespace and match lowercase spelling
3. If you expect a custom backend, verify the binary actually includes it

var supportedSearchModes = map[string]bool{"none": true, "database": true, "meilisearch": true}
mode = strings.TrimSpace(strings.ToLower(mode))
if !supportedSearchModes[mode] {
    return fmt.Errorf("unsupported search mode %q", mode)
}

When it happens

Trigger: Setting the search config to a string that is not a built-in searcher name — typos like 'meilisearch ' (trailing space), 'MeiliSearch' (case), or a build where that searcher was not compiled in.

Common situations: Editing settings manually or via API with wrong casing/whitespace; using a config value carried over from a fork or plugin that this binary does not include.
