The form that opened the site
Putlocker has always put the search form first. The 2015 front page opened with it: a Section switch for all, movies or TV shows, a Title box, a Director box, a Starring box, a Years range and a row of genre boxes. That form is back on the search page, and it does the same job it did then: you describe what you remember and the results narrow until the film you meant is at the top.
Start with the box that matches what you know. If you know the name, type it and press Show results. If you only remember who was in it, use Starring. If you know it was a Nolan film but cannot place the title, use Director. Each box narrows the list on its own, and they combine: a Starring name plus a genre plus a decade is usually enough to find a film you last saw ten years ago.
Title: half a name is enough
The Title box matches the start and the middle of a name, in English or in the original language, and it understands the other names a film goes by. "Philosopher's Stone" and "Sorcerer's Stone" open the same Harry Potter film. "Hunger Games 2" opens Catching Fire. A misspelling that is close enough still finds its film, and if two productions share a name, the year on each card tells them apart: the 2005 Doctor Who and the 2023 one have separate pages, and so do the 2002 Lilo & Stitch and the 2025 film.
Add a season and episode to a series name and the search narrows to that show: "breaking bad s5e14" opens the series whose fifth season has a fourteenth episode, and the season page is one tap further. Words like "watch", "online", "free" and "putlocker" are ignored, so you can paste a phrase from anywhere and still get the film.
Director and Starring
These two boxes search the credits rather than the name. Type "Spielberg" in Director and the list becomes his films in the catalogue, newest first or best rated first depending on the sort you choose. Type "Tom Hanks" in Starring and Cast Away, The Polar Express and Forrest Gump line up together. Surnames alone work. Combine the two when you remember a pairing, such as Scorsese and DiCaprio, and the list is short enough to read in one glance.
Years: a range, not a single year
The years boxes take a from and a to, the way the old form did, because most people remember a period rather than a date. Set 2003 to 2007 and you get the films of Putlocker's first decade of visitors: Troy, The Notebook, Hotel Rwanda, Mean Girls, Batman Begins and The Departed. Set 1994 to 1999 for the nineties. Set 2025 to 2026 for what is new. A single year works too: fill in only the from box, or open the years page and pick one.
Genres and everything else
The Genre menu lists every genre attached to the catalogue: action, adventure, animation, comedy, crime, documentary, drama, family, fantasy, history, horror, music, mystery, romance, science fiction, thriller, war and western, plus the television versions of the same. Most titles carry more than one, so a comedy search finds the action comedies too. The Status menu keeps a series list to shows still returning or shows that have finished. Minimum rating keeps the list to titles rated seven, eight or eight and a half and above by at least fifty TMDB voters. Country and original language do what they say.
Sort decides the order: most popular is the default, and newest, highest rated, recently updated and name A to Z are a click away. Reset clears everything. The address bar carries your search, so you can send a friend a link to "horror, 2004 to 2009, rated seven or higher" and they open the same list.
When the search comes back empty
Remove one box at a time. The most common cause of an empty result is a year that is one off, so widen the range first. The second is a title in another language: try the English release title, or the original one. The third is a name that belongs to a series when you searched movies, or the reverse; switch the Type menu to All. And if the film is genuinely missing, the A-Z list shows the whole catalogue in one scroll, which settles it in a minute.
