textssuch

Textssuch is a modular text processing and search framework designed to enable rapid pattern matching and semantic querying across large text collections. It provides a command-line interface, an embeddable library, and a lightweight query language intended for log analysis, data cleaning, and exploratory text research.

Originally conceived by a small team of developers, textssuch emphasizes speed and composability. The project is distributed under the MIT License and provides binaries for major platforms as well as a language-agnostic API for integration into other tools.

Key features include tokenization with language detection, optional stemming and lemmatization, stopword handling, and optional indexing for repeated queries. It supports boolean, phrase, proximity, and regular-expression queries, along with fuzzy matching and scoring. The system can operate in streaming mode and accepts JSON, CSV, and plain text.

The query language uses a simple syntax with quoted phrases, operators such as AND, OR, NOT, and field qualifiers like field:value. A programmatic API is available in Python, Rust, and JavaScript for embedding within applications.

Usage examples emphasize clarity and reproducibility: textssuch -q 'error AND timeout' logs/*.log -o results.json, or textssuch -q 'status:fail OR status:critical' data.csv | head. The tool focuses on analysis workflows rather than serving real-time search, and heavy regular expressions may impact performance.
