Another tab can contain the exact answer you need. It can also be a comfortable way to postpone forming your own question. Before searching again, write the uncertainty in one sentence.
Are you choosing between alternatives, checking a factual claim or avoiding an uncomfortable first attempt? Those tasks need different information. A precise question makes it easier to recognise an adequate answer and stop collecting material.
Set a stopping condition
Suppose you are choosing a reporting file for a small team. Write the essential requirements: it must open in the available software, support the necessary records and be understandable to its intended user. Testing one candidate against those conditions may contribute more than comparing fifteen more products.
For factual work, an adequate answer needs suitable evidence. A convenient sentence is insufficient when a claim is technical or consequential. Use a reliable original source and check its scope.
Turn information into a move
When you finish searching, record what changed in your understanding and what you will do because of it. Research without an immediate action can still have value; give that exploration an honest purpose of its own.
Keep a parking place for interesting material unrelated to today's question. You can explore it deliberately later. Curiosity deserves room; a deadline deserves a boundary. Choosing between them is more useful than treating every open tab as unfinished work.
