Yossi Tamari commented on NUTCH-2611:
-------------------------------------
I will submit a PR that optionally adds a new-line after block-level elements,
but also leaves the currently-added spaces. Perhaps we should also make this
behavior optional, alternatively adding spaces only after a subset of tags, but
I don't think there is a reliable method to discern which tags apply.

> Key: NUTCH-2611
> URL: https://issues.apache.org/jira/browse/NUTCH-2611
> Project: Nutch
> Issue Type: Improvement
> Components: parser
> Affects Versions: 1.14
> Reporter: Yossi Tamari
> Priority: Major
>
> Currently, the HTML and Tika parser only add newlines following text-nodes
> that contain only whitespaces (e.g </span> <span>), but not based on what the
> tags are, so for example a </div><div> will not add a new line.
> While some applications do not differentiate between a space and a new line,
> many others see the semantic difference (two following words in the same
> sentence are "near", but in separate sentences they are not).
> I believe adding newlines after block-level HTML elements, while not a
> panacea, will be an improvement on the current behavior.
> NUTCH-2318 is related to this.
