Hope that helps.

New ICU’s Regular Expressions page.

Search key1 and key2 within each paragraph

Step a) CTRL + H3, search ^(.)*key1(.)*$
with “regular expression” flag activated

Step b) step a has selected all paragraph containing key1.

search (CTRL + H) ^(.)*key2(.)*$
activating both the “only in selection” and “regular expression” flags

Search key1 or key2 within each paragraph

Search (CTRL + H ) ^(.)*(key1|key2)(.)*$
with regular expression flag activated

Only paragraphs with key1 and key2 in the first case and key1 or key2 in the second will be selected.

With a macro, the search with the and connector can carry out the two steps in sequence (or the n steps for n keys connected with and)
