Incorrect Info + Typos in Views from JP Translator

Excuse me for my slow progress, I'm working on the chapter of View right
now.
I found some typos and questions:

1. The closing bracket is missing
Views can be conditionally updated before or after they are queried.
Or, you can choose to use the existing (and possibly out of date, or
stale, index that already exists at the time the query is executed.
For more information, see Section 9.2.4, ³Index Updates and the stale
Parameter².

2. Typo, perfomance.
the time between updating document data and accessing (or updating) a
view will all impact perfomance.

3. Typo, een
You can use the observeoperation to monitor when documents have een
persisted to disk and/or updated in the index.

-stale.html

4. Question: Why isn't the document included in view data even if it
is stored on disk? Are committing to disk and indexing the document
have been performed at the same time?
This is because the document has been committed to disk, which is the
point where documents are indexed.

5. Unit explanation is not intuitive:
"update interval in seconds" vs "default 5000 milliseconds" ->
"update interval in milliseconds" would be correct?
"number of document changes" vs "default 5000 seconds" ->
updateMinChanges should be the number of changed documents instead of
seconds
the update interval in seconds (updateInterval; default 5000
milliseconds), and the number of document changes (updateMinChanges;
default 5000 seconds).
