Key facts

Felo's search process documentation describes translating a question into English before searching the web and summarizing the results.
Its main features documentation describes bilingual queries, summaries assembled from multiple sources, and links with annotations for further research.
Felo's cross-language search guide describes retrieving material written in other languages and translating results into a preferred language.
The developer Chat API reference documents an answer alongside web resources, including each source's URL, title and relevant excerpt.

How does multilingual retrieval work?

Multilingual retrieval means finding information across languages. Felo's cross-language guide describes searching foreign-language material and automatically translating the results. Its examples include German academic papers and Spanish news articles. The guide gives this query:

research papers on healthy eating habits in German

The example specifies the source language inside the request. Felo describes returning German papers translated into the reader's language. This illustrates a distinction useful for reviewing a result: the language of the underlying document and the language of its presentation can differ.

The search process help page describes a sequence of question interpretation, translation into English, web search and summarization. It names articles, websites and journals as information sources. These descriptions explain the documented workflow; they provide no measured coverage rate across languages.

How are sources presented?

Felo's search process documentation describes numbered footnotes that link to original sources. The answer is a synthesized summary, while the footnotes provide a route to the underlying pages. For a website review, opening the linked page allows comparison between the answer's wording and the material it references.

The bilingual search description also mentions links and annotations accompanying information summarized from multiple sources. A review can therefore record the linked page and the statement associated with it, alongside the language of the question. This preserves the connection between a particular answer and the source presented with it.

What does the developer interface expose?

An API is an interface through which software sends requests and receives data. Felo's Chat API documentation describes analyzing a query, searching, ranking and filtering results, then generating an answer from those sources.

The response fields make this process inspectable: data.answer contains the answer, data.query_analysis.queries contains optimized search queries, and data.resources lists web sources used to generate the answer. Each resource has link, title and snippet fields. These are documented developer response fields; the product help describes the reader-facing presentation through footnotes.
