French Wikipedia is the key data source for finding European actors' full birth names
Director-Film-Actor triangulation — locate the target actor through the director's other works
Two-phase search — first find the actor's stage name, then specifically search for their full birth name
Always add Bollywood/Hindi film/Indian actor keywords when searching for Indian actors
Track Indian actors through family chains — grandfather/father/spouse relationships are key indirect clues
Entity hypothesis — guess candidate Indian actors first, then verify against question constraints
Track from one entity to a related entity through multi-step searches — author to article to mentioned person/place
Use quotation marks around unique phrases or titles from blog posts for exact-match searching
