When a shopping search turns a short query into a longer English phrase, it may be trying to match the words sellers use in product listings—not produce a literal translation. In a dataset of 941 query pairs described by Ohad Farkash in 2026, the English rewrites often added audience, product-form, or bundle terms. The results show how rewriting worked in this particular, Hebrew-heavy set; they do not prove that longer queries improve search results.
Why a shopping search may expand a translated query
Marketplace search is aimed at finding listings, not preserving every word of a shopper’s original phrasing. A literal translation can miss the terms sellers use to identify a product or distinguish it from similar items. A rewrite may therefore add a product form or likely audience when those terms make the intended item clearer.
Farkash’s examples show the difference: a query glossed as “skirt” became “women skirt”; “stroller for a baby” became “baby lightweight stroller”; and “shaker” became “protein shaker bottle mixer.” The query “iron” became “garment steamer handheld clothes.” These are examples from the dataset, not a guarantee that each expansion is correct in every shopping context.

Farkash describes 941 pairs in total, 862 of them Hebrew. The figures below summarize the Hebrew subset where specified; they should not be read as prevalence estimates for multilingual shopping searches generally.

| Measure | Reported result |
|---|---|
| English rewrite had more words | 59.5% of Hebrew queries |
| English rewrite had the same number of words | 30.4% of Hebrew queries |
| English rewrite had fewer words | 10.1% of Hebrew queries |
| Average query length | Rose from 2.35 to 3.10 words |
| English rewrites containing an audience term | 37% of English queries |
| English rewrites containing a bundle term | 15% of English queries |
Farkash gives audience words such as “women,” “men,” “baby,” and “kids,” and bundle words such as “set,” “kit,” “pack,” and “pcs.” The figures describe the author’s dataset and analysis, rather than an independently recalculated benchmark.
Why some rewrites get shorter
Not every English query gained words. In examples where phrases such as “free shipping” or “low budget” were removed, Farkash interprets them as filters rather than terms identifying the product itself. That explanation fits those examples; it does not establish that all search systems treat conditions or filters the same way.

What the dataset can—and cannot—tell you
The rows combine hand-curated mappings, mappings learned and retained by the engine, and a sample of real searches, according to Farkash. Each row includes the shopper’s query, its language, and the English query used to retrieve the intended products. The article identifies public copies on Kaggle, Hugging Face, and Zenodo (DOI 10.5281/zenodo.22930843), and says an analysis notebook is on Kaggle.

- It does not establish retrieval gains: The article says retrieval quality was not measured for each row, so the word-count increase is not evidence that expansion improved relevance or success.
- Its language coverage is uneven: Hebrew accounts for 862 of the 941 pairs. Farkash cautions against treating the other-language examples as statistics.
- Some language labels need care: The article notes that some rows labeled “observed” use the language of the page where the search occurred, not necessarily the query’s script or language.
For judging a rewriting system, retrieval success should be assessed alongside fluency or text overlap; those measures answer different questions. It can also be useful to separate curated, high-traffic “head” queries from generated long-tail queries. Farkash describes using a language model and caching repeated rewrites for the latter, but that account is not an independently audited system evaluation.

Literal translation or product-aware rewriting?
A literal translation is useful when preserving the shopper’s wording is the priority. Product-aware rewriting can be more useful when the goal is to match marketplace terminology, provided added terms clarify rather than distort intent. The examples and counts support the distinction between those goals, but they do not identify a universally better approach. As Farkash puts it in his October 1, 2026 article, “It is expansion, not translation.”
