# llama.cpp/examples/retrieval
Demonstration of simple retrieval technique based on cosine similarity
More info:
https://github.com/ggerganov/llama.cpp/pull/6193
### How to use
`retieval.cpp` has parameters of its own:
- `--context-file`: file to be embedded - state this option multiple times to embed multiple files
- `--chunk-size`: minimum size of each text chunk to be embedded
- `--chunk-separator`: STRING to divide chunks by. newline by default
`retrieval` example can be tested as follows:
```bash
`build`: rename main → llama-cli, server → llama-server, llava-cli → llama-llava-cli, etc... (#7809) * `main`/`server`: rename to `llama` / `llama-server` for consistency w/ homebrew * server: update refs -> llama-server gitignore llama-server * server: simplify nix package * main: update refs -> llama fix examples/main ref * main/server: fix targets * update more names * Update build.yml * rm accidentally checked in bins * update straggling refs * Update .gitignore * Update server-llm.sh * main: target name -> llama-cli * Prefix all example bins w/ llama- * fix main refs * rename {main->llama}-cmake-pkg binary * prefix more cmake targets w/ llama- * add/fix gbnf-validator subfolder to cmake * sort cmake example subdirs * rm bin files * fix llama-lookup-* Makefile rules * gitignore /llama-* * rename Dockerfiles * rename llama|main -> llama-cli; consistent RPM bin prefixes * fix some missing -cli suffixes * rename dockerfile w/ llama-cli * rename(make): llama-baby-llama * update dockerfile refs * more llama-cli(.exe) * fix test-eval-callback * rename: llama-cli-cmake-pkg(.exe) * address gbnf-validator unused fread warning (switched to C++ / ifstream) * add two missing llama- prefixes * Updating docs for eval-callback binary to use new `llama-` prefix. * Updating a few lingering doc references for rename of main to llama-cli * Updating `run-with-preset.py` to use new binary names. Updating docs around `perplexity` binary rename. * Updating documentation references for lookup-merge and export-lora * Updating two small `main` references missed earlier in the finetune docs. * Update apps.nix * update grammar/README.md w/ new llama-* names * update llama-rpc-server bin name + doc * Revert "update llama-rpc-server bin name + doc" This reverts commit e474ef1df481fd8936cd7d098e3065d7de378930. * add hot topic notice to README.md * Update README.md * Update README.md * rename gguf-split & quantize bins refs in **/tests.sh --------- Co-authored-by: HanClinto <hanclinto@gmail.com>

```
This chunks and embeds all given files and starts a loop requesting query inputs:
```
Enter query:
```
On each query input, top k chunks are shown along with file name, chunk position within file and original text:
```
Enter query: describe the mit license
