Warning: I will close the issue without the minimal init.vim and the reproduction instructions.

Problems summary

Some items disappear on filtering. In my case, in file_rec sources.

How to reproduce the problem from neovim/Vim startup (Required!)

1. Create experiment directory
2. mkdir a; cd a
3. Create items should be ignored.
4. mkdir -p vendor/bundle/example

for i in `seq 1 1000`; do touch vendor/bundle/example/${i}.txt; done

6. Create some items should be detected because their path don't contain vendor/bundle
7. mkdir vendor/test
8. touch vendor/test/a.txt
9. touch a.txt

Launch Neovim and install plugins at first.

1. nvim
2. :call dein#install()

Execute ddu feature.

:call ddu#start(#{ sources: [#{ name: 'file_rec', params: #{ ignoredDirectories: ['.git', 'node_modules'] } }] })

At first, all items that I expect to be visible exist. There is no vendor/bundle/* item.

Like below:

vendor/test/a.txt
a.txt

Input ve in the filter window. All items will disappear.

[Shougo]

It is the feature of matcher_substring.

Please see the documentation.

            *ddu-filter-matcher_substring-param-limit*
limit (number)
        The filter limit value.
        If filtered items length is bigger than it, the filter is
        ignored.

        Default: 1000

solution: You can change the order of filters.
