I\'m using ndb.Model. The Search API has the following field classes:
TextField : plain text
HtmlField : HTML formatted text
AtomField : a string wh
Use unique identifiers for each "tag". Then you can create a document like:
doc = search.Document(fields=[
search.TextField(name='tags', value='tag1 tag2 tag3'),
])
search.Index(name='tags').put(doc)
You can even use numbers (ids) as strings:
doc = search.Document(fields=[
search.TextField(name='tags', value='123 456 789'),
])
And query using operators as you wish:
index = search.Index(name='tags')
results = index.search('tags:(("tag1" AND "tag2") OR ("tag3" AND "tag4"))')
