by collection, issn from date to until another date and a period like 7 days.

       [-h] [-x] [-p PERIOD] [-f [FROM_DATE]] [-n] [-u [UNTIL_DATE]]
       [-c COLLECTION] [-i ISSN] [-d]
       [--logging_level {DEBUG,INFO,WARNING,ERROR,CRITICAL}]

optional arguments:
  -h, --help            show this help message and exit
  -x, --differential    Update and Remove records according to a comparison
                        between ArticleMeta ID's and the ID' available in the
                        search engine. It will consider the processing date as
                        a compounded matching key
                        collection+pid+processing_date. This option will run
                        over the entire index, the parameters -p -f -u will
                        not take effect when this option is selected.
  -p PERIOD, --period PERIOD
                        index articles from specific period, use number of
                        days.
  -f [FROM_DATE], --from_date [FROM_DATE]
                        index articles from specific date. YYYY-MM-DD.
  -n, --load_indicators
                        Load articles received citations and downloads while
                        including or updating documents. It makes the
                        processing extremelly slow.
  -u [UNTIL_DATE], --until_date [UNTIL_DATE]
                        index articles until this specific date. YYYY-MM-DD
                        (default today).
  -c COLLECTION, --collection COLLECTION
                        use the acronym of the collection eg.: spa, scl, col.
  -i ISSN, --issn ISSN  journal issn.
  -d, --delete          delete query ex.: q=*:* (Lucene Syntax).
  --logging_level {DEBUG,INFO,WARNING,ERROR,CRITICAL}, -l {DEBUG,INFO,WARNING,ERROR,CRITICAL}
                        Logggin level

optional arguments:
