Dataset view capability of searching files within the dataset does not work as expected

What steps does it take to reproduce the issue?

• When does this issue occur?

When I go to a dataset detail view https://demo.dataverse.org/dataset.xhtml?persistentId=doi:10.70122/FK2/VMUDWY
And this dataset contains many files
And one of the files has the name `Captura de pantalla`
And I search in the dataset view the word `aptura`
I expect to find this file in the search results
But this file is not appearing

Probably the cause is because the search engine is indexing words from the beginning and does not find parts of the words

• What page does this occur?
