Fix recent queries not working for DQL and Lucene

[ahopp]

Description

Fixes the Recent Queries button not working for DQL and Lucene query languages in the Discover plugin.

Issues Resolved

Fixes #10810

Root Cause

The Recent Queries feature was broken for DQL (kuery) and Lucene queries due to two issues in the query editor (src/plugins/data/public/ui/query_editor/query_editor.tsx):

Visibility condition bug: The RecentQueriesTable component visibility was gated by isRecentQueryVisible && useQueryEditor. The useQueryEditor flag is false for DQL and Lucene queries, preventing the dropdown from ever showing.

Missing history save: The onSubmit function never called queryString.addToQueryHistory(), so queries were not being saved to history in the first place.

Changelog

src/plugins/data/public/ui/query_editor/query_editor.tsx

Line 487: Removed && useQueryEditor from RecentQueriesTable visibility condition

• Before: isVisible={isRecentQueryVisible && useQueryEditor}
• After: isVisible={isRecentQueryVisible}

Lines 157-160: Added queryString.addToQueryHistory() call in onSubmit function

 // Add query to queryString history for Recent Queries feature
 if (currentQuery.query?.trim()) {
   queryString.addToQueryHistory(currentQuery, dateRange);
 }

Testing

Tested locally with DQL and Lucene queries in the Discover plugin:

• Executed multiple DQL and Lucene queries (e.g., order_id:570663, day_of_week:Thursday)
• Clicked the "Recent queries" button
• Verified that the dropdown appears and shows all executed queries
• Confirmed queries can be re-run by clicking them from the list

DQL:

Lucene:
