For targeted searches based on specific technologies, follow these steps:

1. Navigate to the "Technologies" tab within the left-side filters.

2. Use the search function to find and select specific technologies you wish to include or exclude from your search.

3. Opt for "one of the following" to broaden your search to include contacts from companies using any of your selected technologies.

4. Choose "all of the following" for a more focused search, where only contacts from companies using all your selected technologies simultaneously will be included. Note, selecting "all of the following" significantly narrows down your results as it looks for contacts in companies that utilize all listed technologies at the same time.

This approach allows you to precisely tailor your prospect list based on technological criteria, enabling more strategic targeting.
