Google App Engine - Using Search API Python with list fields

Question

I\'m using ndb.Model. The Search API has the following field classes:

    TextField : plain text
    HtmlField : HTML formatted text
    AtomField : a string wh         


        

Answer 1

You should add as many fields as 'tags' you have, all with the same field_name:

doc = search.Document(fields=[
    search.TextField(name='tag', value=t) for t in tags
])

As in the docs:

A field can contain only one value, which must match the field's type. Field names do not have to be unique. A document can have multiple fields with the same name and same type, which is a way to represent a field with multiple values. (However, date and number fields with the same name can't be repeated.) A document can also contain multiple fields with the same name and different field types.

Answer 2

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"))')
