Start with the requirement, not the tool name
Before searching, ask whether every tile must be used. An exact anagram rearranges the entire rack without adding or dropping a letter. A subset search permits unused tiles. Both modes must respect repeated letters. The distinction matters more than the name of a tool: websites sometimes use anagram solver, unscrambler and word finder interchangeably.
Work through LISTEN
LISTEN has six different letters. SILENT, ENLIST and TINSEL use all six, so each passes exact mode. LIST uses L, I, S and T but leaves E and N unused, so it passes subset mode only. Enter LISTEN with exact mode enabled, then turn exact mode off and set minimum and maximum length to four. The second search asks a different, narrower question about word length.
Length alone is not enough
A six-letter candidate is not automatically an anagram of LISTEN. LETTER has the right length but needs two Es, two Ts and an R. Those tiles are unavailable. Matching therefore requires both a compatible length and a count for every letter. This also explains why seeing a letter somewhere in the rack does not authorize using it twice.
Check a repeated-letter rack
LEVEL contains two Ls, two Es and one V. It can form LEVEL in exact mode and EEL in subset mode. EVE cannot be made from LEV because it needs a second E. LEV? can form EVE in subset mode by spending its blank on E, but fails exact mode because the L remains unused. Counting the leftover tiles is an easy final check.
Use exact length inside subset mode
Suppose a seven-tile rack must fit five open squares. Choose subset mode with both length limits set to five. Exact mode means using all seven tiles, not merely finding words of a chosen length. In this tool, selecting exact mode disables the range controls and uses the rack length so those requirements cannot contradict each other.
Known positions are a separate constraint
A crossword pattern C?A?E fixes three letter positions. CRATE fits; REACT does not, even though both use the same printed letters. This rack solver cannot preserve positions. Use a position-aware tool for that task, then compare definitions with the clue. Adding a blank does not turn an unordered search into a crossword solver.
Two checks to try
Can LISTEN make LIST in exact mode? No: two letters remain. Can LEV? make EVE using every tile? No: the blank provides the second E, but L remains. Both become possible in subset mode. Explain both the letter supply and any leftover tiles before accepting an answer.
Verify meaning after matching
A matching result establishes that the tiles fit the word list used here. It does not establish current tournament eligibility, suitability for a classroom assignment, or a clue definition. Look up unfamiliar meanings, check the rules for your activity, and keep a record of useful patterns you can recognize without the solver next time.

Quick review
The strongest habit is to separate hard constraints—letter counts, length, fixed positions—from helpful clues such as frequency and familiar patterns. Use the tool to narrow possibilities, then use meaning and context to choose.
