[ENHANCEMENT] Wildcard support about marqo HOT 3 OPEN

Hi @jess-lord . Thanks for raising this issue. Is your requirement to search only based on a filter with no query? Or do you intend to use the wildcard potentially as part of a string? e.g. q="somevalue*" for a prefix search

In the meantime, I believe having q="Trolling" with a filter could in fact give you the desired outcome. Your query might match content=Troll due to linguistic processing (stemming), but the filter will eliminate those results.

Here's an example I just tried

ix.add_documents(
    documents=[
        {
            '_id': '1',
            'title': 'Trolling',
            'topic': 'Fun'
,        },
        {
            '_id': '2',
            'title': 'Troll',
            'topic': 'Fun'
,        }
    ],
    tensor_fields=[]
)

response = ix.search(q='Trolling', limit=10, search_method="lexical", filter_string='NOT topic:(Trolling) AND title:(Trolling)')

response['hits']

Results:

[{'title': 'Trolling',
  'topic': 'Fun',
  '_id': '1',
  '_score': 0.1823215567939546,
  '_highlights': []}]

As you can see, this didn't return the document with title=Troll.

@farshidz Thanks for looking into this. I'm looking for exact token matches, so "troll" should match "the troll under the bridge" but not "the trolling of online forums". The use case is to search marqo document content for important keywords that need an exact match. So the filter would target the "content" property of the documents. Maybe a more abstract example is easier:

ix.add_documents(
    documents=[
        {
            '_id': '1',
            'content': 'lorem ipusm abc1 lorem',
            'topic': ''
,        },
        {
            '_id': '2',
            'content': 'lorem ipusm abc110 lorem',
            'topic': ''
,        }
    ],
    tensor_fields=[content]
)

In this example my objective is to filter the index for docs with content of abc1, and tag all matching results with a topic of genreA, and tag docs containing abc110 with genreB. When filtering for "abc1" I don't want to get this second document.
