## Explanation

This formula relies on the FILTER function to retrieve data based on a logical test. The *array* argument is provided as B5:D14, which contains the full set of data without headers. The* include* argument is based on a logical test based on the ISNUMBER and SEARCH functions:

```
ISNUMBER(SEARCH("rd",B5:B14))
```

In brief, the SEARCH function is set up to look for the text "rd" inside the street data in B5:B14. Because this range includes 10 cells, 10 results are returned. Each result is either a number (text found) or a #VALUE error (text not found):

```
{#VALUE!;11;#VALUE!;#VALUE!;13;#VALUE!;#VALUE!;18;17;#VALUE!}
```

And the resulting array returned to the FILTER function as the *include* argument:

```
{FALSE;TRUE;FALSE;FALSE;TRUE;FALSE;FALSE;TRUE;TRUE;FALSE}
```

This array is used by the FILTER function to retrieve matching data. Only rows where the result is TRUE make it into the final output.

Finally, the *if_empty* argument is set to "No results" in case no matching data is found.

### Wildcards

The SEARCH function supports wildcards, so the filter logic can include these characters.

### Case-sensitive

For a partial match, case-sensitive filter, you can adjust the formula to use the FIND function instead of SEARCH like this:

```
=FILTER(rng1,ISNUMBER(FIND("TXT",rng2)))
```

*Note: FIND is case-sensitive, but does not support wildcards.*
