So if I search using

(?=.*Error)(?=.*Foobar1)(?=.*Foobar2)

With regular expression and newline checked. I do see it boil down to the files I am interested in. My only other need is to see all the lines associated/contained with the AND. …

The first table in the FAQ is just showing the logic for matching all of those terms. Later down in the FAQ, there is another table which explains how to find the exact line that matches all of those terms. In your case, the AND would be (?-s)(?:(?=.*Error)(?=.*Foobar1)(?=.*Foobar2))^.*(?:\R|\z)

or, using the Find Results via Find All in Current Document:

dummy example file to show it working:

Blah Error Blah Foobar1 blah Foobar2
Blah Warning blah Football1 blah Football2
Blah Foobar2 blah Foobar1 blah Error order doesn't matter
Blah Error blah Foobar1 blah Footbark2 won't match because it doesn't have all three

(?=.*Error)(?=.*Foobar1)(?=.*Foobar2)

With regular expression and newline checked. I do see it boil down to the files I am interested in. My only other need is to see all the lines associated/contained with the AND. It just shows the chunk of text from the beginning of the file to the first match it finds which in this example is Foobar1. I was more interested in seeing each line (e.g. also Error) that matched. I didn’t see this in the help page. Maybe this is not possible but thought I would ask. Thanks for all your help so far!

Any keywords to require all the hits

The “logic gates” link I gave you includes how to do “AND” (“requires A and B and C”)

With logic, you can create any more complicated rules you want (like “(A AND B) BUT NOT (C OR D)”) by nesting inside the constructs. Play with the expressions from that “logic gates” page, see what they do; try nesting them; get a feel for how the logic works together. Soon, you’ll be able to craft the combinations that most help you with your data.

Star Trek IV reference? :-)

It only took 5 years for people to finally understand me correctly. I guess I made it too obvious this time, with finally adding the third alternative. :-)

Find What = \b(George|Gracie|whale)\b

The Search Results panel is designed to only show one line per match (even if you do a search expression that matches text that crosses over lines, it will only show the first line of the match). There isn’t a way to increase context.

Support for multiple keywords would be an additional plus.

The existing regular expression (regex) feature already handles that.

• Find What = \b(George|Gracie|whale)\b
  • the \b matches “word boundary” so it would match George but not Georgene, etc.
  • the (...) makes a group - without this logical group, the \b would have to be repeated at the beginning and end of each word, like \bGeorge\b|\bGracie\b|\bwhale\b
  • the | means “OR”
  • translated to english, this Find What means “match a boundary, then George or Gracie or whale, then another boundary”
• Match Case = off
• Search Mode = Regular Expression
• . matches newline = off

From our FAQ section, the Generic Regular Expression formula FAQ links to a post Generic Regex: Logic Gates for Regular Expressions which explains how to match lines with AND, OR, Exclusive-OR, and similar logical constructs.
