- quick fix of search API when using with advanced search
WalkthroughThe controllers now identify supported PFQL query prefixes. Recognized queries are transformed for Elasticsearch or evaluated into predicates. Legacy, empty, blank, and unrelated queries retain their existing handling. ChangesPFQL search handling
Estimated code review effort: 3 (Moderate) | ~20 minutes Merge Risk: 🟡 Moderate · up to The change can still return tasks when a filter guarantees no matches and can produce counts that do not reflect advanced-search filtering; inputs such as Sequence Diagram(s)sequenceDiagram

`@src/main/java/com/netgrif/application/engine/workflow/web/AbstractTaskController.java`:
- Around line 388-400: Update startsWithPfqlPrefix in
AbstractTaskController.java (lines 388-400) and the corresponding helper in
WorkflowController.java (lines 290-302) so the where match requires a token
boundary, accepting where followed by whitespace or the end of the query while
rejecting values such as wherex; preserve the existing prefix and exact-match
behavior.
- Around line 202-215: The search aggregation in AbstractTaskController must
preserve the null no-match result from LegacyTaskSearchService.buildSingleQuery
instead of discarding it with filter(Objects::nonNull). Detect that result
before combining predicates and return an empty page or add an explicit false
predicate, ensuring both mixed and single-request searches return no tasks when
the legacy group query guarantees no match.
- Around line 184-191: Apply the existing PFQL-to-Elasticsearch conversion used
in AbstractTaskController to requests before both elasticTaskService.count and
elasticCaseService.count calls, ensuring each request is evaluated with
SearchUtils.evaluateQuery and replaced with evaluator.getFullElasticQuery when
isPfqlQuery returns true. Update the corresponding count flow in
WorkflowController as well; both listed sites require the same preprocessing.

Transform PFQL queries before both count calls.
ElasticTaskService.count and ElasticCaseService.count pass requests directly to Elasticsearch query construction without PFQL evaluation. Apply the same conversion before elasticTaskService.count and elasticCaseService.count.

Preserve the legacy no-match result.
LegacyTaskSearchService.buildSingleQuery returns null when its group query guarantees no match. Line 212 discards that state. If another request has a predicate, the search can return its matches instead of no tasks. If it is the only request, the final predicate has no legacy restriction.
Detect this legacy no-match result before filtering predicates. Return an empty page or add an explicit false predicate.

Require a token boundary after where.
startsWith(prefix + " where") classifies case wherex as PFQL. That string does not contain the where keyword. The controllers then send a legacy query to the PFQL evaluator.
Require a keyword boundary after where in both helpers.
