I have

• Tested with the latest release
• Tested with the current master branch
• Searched for similar existing issues

Expected behaviour

Able to request to Solr server and getting response

Actual behaviour

Getting error as follows

SolrError: Solr responded with an error (HTTP 400): [Reason: TaggerRequestHandler requires text to be POSTed to it]

Steps to reproduce the behaviour

1. Follow the steps in https://lucene.apache.org/solr/guide/7_4/the-tagger-handler.html#tutorial-with-geonames
2. Run the following code

import pysolr
solr = pysolr.Solr('http://localhost:[port]/solr/geonames')
results = solr.search('New York City', search_handler="/tag", **{
    "overlaps": "NO_SUB",
    "tagsLimit": 5000,
    "fl": "id,name,countrycode",
    "wt": "json",
    "indent": "on"
})

Configuration

• Operating system version: Ubuntu 16.04
• Search engine version: 7.5
• Python version: 3.6
• pysolr version: 3.8.1

This sounds like it's working correctly – the search method uses the select handler and expects a certain result format. It sounds like what you need is adding a separate tag handler which follows that API just as for older interfaces like more-like-this: https://github.com/django-haystack/pysolr/blob/master/pysolr.py#L801
