Grammatical forms
The search engine understands all forms of Czech and Slovak words
Key features: Czech language · Declension · Conjugation · Stemming
One product, many forms
Czech and Slovak words decline and conjugate. The system automatically recognises all grammatical forms, so "boty", "bot", "botách", or "botami" all find the same products.
What the system recognises
Noun declension
bot, boty, botů, botám, botách, botami – all forms find the same product.
Number (singular/plural)
"phone" and "phones" lead to the same results.
Gender (masculine/feminine/neuter)
Gender recognition for correct adjective matching.
Cases (1st-7th case)
The system normalises all cases to the base form of the word.
Adjectives
"blue", "blue (fem.)", "blue (neut.)", "blue (pl.)" – all forms work.
Verbs and conjugation
Searches such as "run", "I run", "ran" lead to running products.
How it works technically
We use a technique called stemming, optimised for Czech and Slovak:
- The word is reduced to its base form (stem)
- The search runs against that stem
- All grammatical forms lead to the same stem
- Results include products containing any form of the word
Example:
Customer searches for: "black shoes"
The system normalises to: "black + shoe"
It finds products containing: "black shoes", "black shoe", "with black shoes", etc.
This technology is essential for Czech online stores because Czech has very complex grammar and customers naturally use various word forms.
