Search for a list of User Profiles that meet a certain condition

I have looked high and low for this and am just not able to find what I'm looking for. I am assisting a group of girls in making this app and we are stuck. I have an app that allows users(this is intended for nonprofits) to create a profile, and fill it out with basic information (phone number, address, etc.) Then they are asked for "needs" they might have like clothing or food.

I used a Tinywebdb to create the profiles. So far profile creation works great and its saving the information. Users can log back in and update the information as well.

I'm running into a problem on my last step. I want an individual user to be able to "search" these user profiles and see who currently needs food/clothing. So what I'm thinking is if the food or clothing textbox isn't blank- the person searching would be able to view profiles in a list that meet a certain condition.

I currently have a screen with a listpicker option where the user can select "clothing" or "food". I'm just not sure how to get it to pull user profile data for multiple users. I've combed through everything I can find on user profiles and this is where I am getting stuck.

Thank you for any help!

Easiest thing to do would be to download all the profiles and data, set this to lists, then you can search the lists to return the matching profiles.

Without seeing how you are storing your profiles in tinywebdb, difficult to offer further advice.

TinyWebDB is a tough database to use for aggregating data in a way you can loop over.

It lacks tag lists and the ability to ask for ranges of tags and values.

If you store collections of data under single tags, you have to make up your own locking mechanism to deal with overlapping updates to the collections.

I would have used a spreadsheet component instead.

That said, here are two links to ways to deal with this:
