How search works

Every question goes through four stages

Meaning and wording both matter. The system does not rely on a single search method; it re-scores the results of several before showing them.

1Semantic searchFinds passages that are close in meaning to the question, even if they are worded differently.pgvector
2Keyword searchFinds exact terms, codes and names — where even a single letter matters.BM25
3Result fusionTurns the two lists into one, based on each result's rank in each.Reciprocal Rank Fusion
4Final rankingRe-scores each candidate against the question itself and returns the most relevant passages together with their source.Multilingual Cross-Encoder

All four stages run on your organization's server. Every new document enters this pipeline the moment it is uploaded; the whole index never needs to be rebuilt.

Built for Persian

Details that generic tools miss

Search that understands Persian writing

A Persian word can be written several ways (half-space, Arabic "ی" and "ک", three digit systems). The system treats them all as one, so no result is lost because of a different keyboard.

Phone calls, with their own ID card

Each call's details are extracted from the recorded file name and stored next to the transcript: direction, counterparty number, extension and time. So you can ask who called about a topic, and when.

Homophone letter correction

Letters like "ق" and "غ", or "ز", "ذ", "ض" and "ظ" sound the same, and no listening model can tell them apart from audio. The system corrects these common errors after transcription.

Roadmap

Next step: written answers, still with no data leaving

Today the system shows the most relevant passages together with their source. The items below are not available yet; they are being planned or built.

In progress

A local large language model

Setting up a language model on a dedicated GPU server, so the system writes a complete, fluent answer instead of only showing relevant passages — still without connecting to any external service.

Planned

Model tuning for each organization

Tuning the model on the organization's own knowledge and real questions, so answers match that organization's terminology and way of working.
