This topic explains how certain configuration settings can affect the search results.

Note The information in this topic is intended to:
  • Help Collibra Data Intelligence Cloud administrators understand how the search configuration settings affect the search results.
  • Help other Collibra users understand why certain search queries might not provide the expected results.

For more information, go to the respective sections on customizing the search index, boosting, stop words, and the exact match features.

Prerequisite

An asset named On The Go exists in your Collibra environment.

Search text

Enter the following search text: On The Go

Result

The asset On The Go is found.

In the following image, the word Go is shown in green. This indicates that Go is the match that produced the result. The words On The, which are shown in black, did not produce a match.

Furthermore, if you enter the search text On The, the asset On The Go or any other asset is not found. This is because "on" and "the" are stop words, which are filtered from indexing and searches.

Tip The best way to ensure thorough and intuitive search results is to name your assets, domains, and communities as thoughtfully as possible.

Search text

Enter the following search text: marketing team summit

The search engine interprets your search text as follows: "marketing" OR "team" OR "summit*"

Notice the wildcard (asterisk) at the end of the word "summit". This is determined by the default UI search appends wildcard setting, which adds the wildcard to the end of the search text.

Result

  • An asset named marketing_campaign_xyz is not found.
  • An asset named team123 is not found.
  • An asset named summit_planning is found.

To find the assets named marketing_campaign_xyz and team123, you must add the wildcard after each word as follows: marketing* team* summit. The search engine then interprets your search text as follows: "marketing*" OR "team*" OR "summit*".
