Bug: People Search Not Working: "Problem completing query" Error When Searching

Bug Description

Bug Description

Search functionality in the People & Groups tab is not working. When attempting to search for people, an error occurs and no results are returned.

Steps to Reproduce

1. Navigate to the People & Groups tab
2. Type any search term in the search box
3. Observe the error message and lack of results

Current Behavior

• Error message appears: "There was a problem completing this query"
• No people are returned in the results
• When searching for people within an insight, a similar error occurs with additional technical details related to illegal Float64 type

Expected Behavior

• Search should return matching people results
• No error message should appear

Error Messages

1. In People & Groups tab:
   "There was a problem completing this query"

2. In Insights:
   "There is a problem with this query"
   Detailed error: "Illegal type Float64 of argument of function ilike"
   [Full error message included in original ticket]

Additional Context

The error appears to be related to type handling in the search query, specifically around Float64 type conversion when using the ILIKE function.

Start by reproducing the failure in the People & Groups tab and in People searches within Insights. Trace the search query handling around the reported illegal Float64 argument passed to ILIKE; done means both searches return matching people without either error message.
