Add fuzzy_search_swap and grep_swap for callers that keep two result buffers. Each call fills next, swaps it into previous, and returns a borrow of the page. Neovim uses both APIs while the picker is open.
letmut previous = SearchBuffer::default();letmut next = SearchBuffer::default();for input in inputs {let query = parse_grep_query(input);
picker.grep_swap(&query,&options,&mut previous,&mut next);render(&previous.page, previous.metadata());}
The page vectors grow only when their capacity is too small. Matcher scratch and owned grep lines can still allocate.
Fuzzy search retains matching candidate IDs beyond the visible page. Grep records one bit per file it can skip. A compatible refinement keeps the original scan time. An index change or the 15-second TTL ends candidate reuse. Configure the TTL with SearchBuffer::with_ttl or Neovim’s search_ttl_ms. An unreported file edit can remain hidden until expiry.
Existing Criterion cases on an Apple M5 Max. Each row uses the same fixture, final query, and options for all three measurements. Both swap runs warm the destination with the preceding keystroke outside the timer. Only the filled run keeps the previous candidates.

Filename searches used controller, four threads, no current file, a 50-item page, and 20 samples. The existing grep fixture returned 40,000 matching lines from 800 files, with 30 samples per case.
The 10,000-path slowdown repeated on a second run (322 µs empty, 427 µs filled). Fuzzy-typo grep changed direction on its rerun (9.08 ms empty, 8.80 ms filled), so its effect here is inconclusive.
Use the original Criterion ID to run one case and both of its variants.

It looks like this branch is under active development. To avoid overwhelming you with review comments due to an influx of new commits, CodeRabbit has automatically paused this review. You can configure this behavior by changing the reviews.auto_review.auto_pause_after_reviewed_commits setting.
The change adds reusable buffers for fuzzy file, directory, mixed, and grep searches. Search metadata and index revisions govern reuse. Neovim and Lua picker flows pass buffers between searches. Tests compare buffered results with one-shot searches.
Changes: Search buffer reuse
Layer / File(s)
Summary
Search buffer metadata and reuse rules crates/fff-core/src/search_buffer.rs, crates/fff-core/src/lib.rs
SearchBuffer stores query metadata and candidate state. Reuse checks include index revision, mode, typo budget, query refinement, and casing. The crate re-exports the buffer types.
File and directory scoring accept optional candidates. Matching stores candidate row indices for later searches and excludes deleted rows from returned results.
Fuzzy search APIs and index revisions crates/fff-core/src/file_picker.rs, crates/fff-core/tests/search_swap.rs
FilePicker adds swap-buffer APIs for file, directory, and mixed searches. Index revisions advance on index changes and mutable file access. Tests compare buffered searches with one-shot results.
Grep reuse and result tracking crates/fff-core/src/grep/*, crates/fff-core/src/types.rs
Grep carries reuse state, skips eligible files, and records misses. The search returns its effective pattern.
Grep swap API and validation crates/fff-core/src/file_picker.rs, crates/fff-core/tests/search_swap.rs
FilePicker adds grep_swap and records reuse metadata. Tests cover grep modes, query edits, file changes, pagination, filters, and result consistency.
The Neovim binding creates a buffered search closure. Lua picker flows pass it to file and grep searches and clear it on close or reset. Configuration sets a 15-second default TTL; 0 disables reuse.

The tombstone path does not advance index_revision. Reuse across tombstone is correct only because deleted rows are filtered at read time. The test discards the result of the "control" search made right after remove_file_by_path. A regression that leaks deleted files would pass.
Assert that components/controller.rs is absent from that page. Compare it with fuzzy_search.

Capture the result of the `fuzzy_search_swap` call immediately after `remove_file_by_path` and assert that its page does not contain `components/controller.rs`. Match the deleted-file check used with `fuzzy_search` while preserving the existing search and swap flow.
The current test covers only two files and checks one result per page. Compare complete fuzzy_search and fuzzy_search_swap results across generated paths and prefix chains, including typo-bearing matches and the u8-to-u16 scoring boundary.
