Fuzzy search in portal (on lookup)

Posted on by fuzzygoose

Hi all,

Have a business requirement to 'fuzzy' search a column. A simple solution that would work for us is to automatically append/prepend wildcares like so `*searchterm*`.

I haven't been able to find a good/clean solution for this. It appears that some of the solutions that are available in the model-driven apps are not available for portals?

Hope to hear your best practice!

Thanks

To create a fuzzy search on a lookup in Power Pages:

Use a Dataverse table. Enable wildcards in your search using the like operator. Update the page dynamically with results using JavaScript.

Steps:

1. Create a FetchXML query in Dataverse:

2. Use a custom web API to expose this query. Ensure it accepts a search term as input.

3. Add JavaScript to your Power Pages site to call this API when the user types in the lookup field:

4. Test the lookup by typing in the field and confirming it dynamically updates with partial matches.

5. Ensure proper security settings on your Dataverse table and API permissions.
