### Real life examples

export all documents into a json file

    ./run.sh -s http://localhost:8983/solr/collection -a export -o /tmp/collection.json

import documents from json

    ./run.sh -s http://localhost:8983/solr/collection -a import -o /tmp/collection.json 

export part of documents, like adding a `fq`  Solr parameter to the export

     ./run.sh -s http://localhost:8983/solr/collection -a export -o /tmp/collection.json --filterQuery field:value

import documents from json but first delete all documents in the collection

     ./run.sh -s http://localhost:8983/solr/collection -a import -o /tmp/collection.json --deleteAll

export documents and skip few fields. In the example the will be skipped the fields: `field1_a`, all the fields starting with `field2_` and all the fields ending with `_date`

     ./run.sh -s http://localhost:8983/solr/collection -a export -o /tmp/collection.json --skipFields field1_a,field2_*,*_date
