advancedFilterdescription onclinicaltrials_search_studiesandclinicaltrials_get_study_count(#47) — anchors theAREA[FieldName]valueshape (wasAREA[]) and demonstrates AND/OR composition with two new examples:AREA[Phase]PHASE2 AND AREA[StudyType]INTERVENTIONALand(AREA[Phase]PHASE3 OR AREA[Phase]PHASE4) AND AREA[StudyType]INTERVENTIONAL. Steers LLM callers away from SQL-styleField = valueshapes that parse but silently return zero matches.path_not_foundrecovery hint onclinicaltrials_get_field_definitions(#48) — promotesquerykeyword search (e.g.,"phase","enrollment") as the primary remedy when a guessed dot-notation path misses.
