# Bilingual Concordancer (Streamlit)

This Space serves a bilingual concordancer with word alignment highlighting.

## Required corpus files

Place these Parquet files in the Space root (same folder as `stwebm_parquet_wa.py`):

- `UNPCwa.parquet`
- `NTURegswa.parquet`
- `SATwa.parquet`
- `VOAwa.parquet`

The app expects these exact filenames.

## Fancy regex mode

`Fancy regex` is implemented via a Rust Polars expression plugin under:

- `rust/fancy_regex_expr_plugin/`

The Docker build compiles this plugin automatically.

## Notes

- `search_history.log` is created at runtime and appended on each search.
- Download exports are available as HTML, DOCX, and XLSX.
