Use Regex in Keyword Boosting to Handle Query Inflexion

SearchUnify
  • Updated

Keyword Tuning is a powerful tool that can be used to change the rank of a document for a query or a related set of queries.

Boost for Query (Precise)


You can be precise with it, so that document X is boosted only for add checkbox.

In this case, the X may or may not turn up for related queries, such as adding checkbox or add checkboxes.

Boost for Query Forms (Comprehensive)



Alternatively, you can choose to be comprehensive and use a regular expression to boost document X for all the forms of add checkbox, so that someone looking for adding checkbox or add checkboxes also gets document X on top.

Regex patterns are extremely useful in languages such as Polish and Russian where nouns declensions are aplenty. They are also a useful tool for Spanish, French, and other languages with complex verb conjugations. You can handle these and other inflexions with regular expressions.

    This is great to know about. Would be great to use Regular Expressions in the search as well, see idea: https://community.searchunify.com/topic/306/regular-expressions-supported

    I'm confused by examples for the . operator and the | operator. Wouldn't reali.ze be read as realiaze, realibze, realicze, realidze...? Also wouldn't realize[s|z]e be read as realizese, realizeze?

    Another question: Is it possible to use regex to account for the order of the words in the search? To use your example, would there be a way to also capture "checkbox adding"?

    Does Regex have an AND operator? This article pictures Regex keyword tuning with the example "Data && Protection." Is this the AND operator? The article doesn't include a list of examples, and there is no AND operator in the chart here.
