If you have a single filter input field and want to search many columns, another approach is to convert the entered string into an array and use each element as a separate search criterion. Eg here I’m using the first word to search several columns:
If I want to use the second word too, I’ll duplicate these, but using {{search.split(" ")[1]}}
and so on.
In this case, I’m searching about 15 columns, so it wouldn’t be practical to combine them into a single column for searching. Having to specify each array element doesn’t seem an ideal solution but I don’t think it’s possible to generate the query dynamically with Wappler. In any case, this solution works well. In this example, the screenshot show only three of about 80 query parameters.
