A long time ago, the Stack Exchange search engine would return posts that matched any one of the search terms. After complaints, a new search engine changed that. Now it only returns posts that match all the search terms.

It is possible to OR combine tags, for example:

But with words this does not work:

The Stack Overflow search help does not indicate any way of combining word searches with OR (it only references OR in combination with tags). The Meta Stack Exchange search help contains the exact same text.

How can I combine searches?

It's not possible with the Stack Exchange search engine. I recommend searching for e.g. site:stackoverflow.com dipimage OR diplib using a regular search engine. Here are the 187 results found by Google.

  • Yes, of course we can use Google. But it's not really the same, you can't distinguish questions from answers containing those words, see votes, see tags attached to the questions, etc. Apr 19, 2019 at 16:45

    @CrisLuengo Unfortunately, this is the current state of things (it's well known that the in-built search lacks in many aspects). If you'd like SE to incorporate a proper OR operator, perhaps make it a feature-request?
