  1. Lesson 1: Decide what autocomplete should suggest

    Choose products, query completions, categories, or content from the search task instead of mixing every result type.

  2. Lesson 2: Make search match how shoppers write

    Test misspellings, abbreviations, and symbols against the catalog, then add targeted mappings where native matching falls short.

Autocomplete and matching translate partial, imperfect, and varied language into credible products or destinations. The business outcome is not more suggestions. It is fewer cases where the store carries the answer but search fails to recognize the query.

This module covers predictive suggestions, submitted-search matching, misspellings, synonyms, abbreviations, symbols, and regression checks. These decisions belong together because an autocomplete suggestion can look correct while the submitted results fail, or native tolerance can solve a typo while a custom mapping creates irrelevant matches. Shopify documents native typo tolerance, query relaxation, and limited partial-word behavior, so the correct starting point is the live platform behavior rather than an assumption.1

Sequence the work by diagnosis. Build a query set from catalog language, customer language, and actual failures. Test predictive and submitted search. Correct product data. Add narrow synonym mappings. Consider a replacement search tool only after repeat, important gaps remain.

Module diagnostic

Choose priority products and write full terms, partial terms, common misspellings, shopper synonyms, abbreviations, and symbol variants. Run every query on phone and desktop. Record suggestions, submitted results, ordering, zero-result states, and false matches. Include a product with a short name and one with several words because native behavior can differ by term and field.1

Small assignment

Create a ten-query regression sheet. For each query, name the intended product or destination, acceptable alternatives, current result, proposed fix, owner, and retest date. Remove mappings that cannot be explained.
