When I use the code
`findall("DD","DDDAADDD")`
I get the response
```julia
2-element Vector{UnitRange{Int64}}:
1:2
6:7
```
But perhaps the answer might include the others, such as `2:3` and `7:8`? What am I missing here? The function seems to miss overlaps.

you have to explicitly request it
```julia
julia> findall("DD","DDDAADDD", overlap=true)
4-element Vector{UnitRange{Int64}}:
1:2
2:3
6:7
7:8
```

OK thanks. I thought I read the REPL help for the function and there was no mention of that option that I could see.

That’s odd, `overlap` is definitely [in the docstring for `findall(::String, ...)`](https://github.com/JuliaLang/julia/blob/a17db2b138b0e042329d2a3fb2efd53c68e2563f/base/strings/search.jl#L519-L520).
But for some reason that isn’t one of the methods for which the docstring is printed in the REPL help?
