curl $account.cloudant.com/foo –X PUT
curl $account.cloudant.com/foo/_design/bar –X PUT –d '{"indexes":{"baz":{"index":"function(doc){index("color",
doc.color); index("size", doc.size);}"}}}'
curl $account.cloudant.com/foo/doc
1 –X PUT –d '{"size": "small", "color": "green"}'
curl $account.cloudant.com/foo/doc2 –X PUT –d '{"size": "large", "color": "green"}'
curl $account.cloudant.com/foo/doc3 –X PUT –d '{"size": "small", "color": "red"}'

4. Searching
curl $account.cloudant.com/foo/_design/bar/_search/baz?q=size:small
curl $account.cloudant.com/foo/_design/bar/_search/baz?q=size:large
curl $account.cloudant.com/foo/_design/bar/_search/baz?q=color:red
curl $account.cloudant.com/foo/_design/bar/_search/baz?q=size:small%20AND%20color:red

5. Pagination
Every search request returns a "bookmark" attribute. Pass this back to Cloudant to get the next "page" of
results.
curl https://$account.cloudant.com/foo/_design/bar/_search/baz?q=*:*&limit=1
curl
https://$account.cloudant.com/_design/bar/_search/baz?q=*:*&limit=1&bookmark=g2wAAAABaANkA

6. Sorting
The "sort" parameter lets you sort results on any indexed field or combination of indexed fields.
curl https://$account.cloudant.com/foo/_design/bar/_search/baz?q=*:*&sort="size<string>"
curl https://$account.cloudant.com/foo/_design/bar/_search/baz?q=*:*&sort="color<string>"

7. Tokenization (https://docs.cloudant.com/search.html)
• Tokenizers break down textual input into tokens for efficient and
flexible searching
• Using an appropriate tokenizer is often critical
• Generic analyzers: standard, email, keyword, whitespace
• Language specific analyzers: english, french, german, spanish,
chinese, dutch...
• You can configure different analyzers for different fields
• Some tokenizers omit common words
• Some tokenizers omit common prefixes or suffixes

8. Tokenization Examples
> curl https://$account.cloudant.com/_search_analyze –Hcontent-type:application/json –d '{"analyzer":"standard",
"text": "rnewson@apache.org"}'
{"tokens":["rnewson","apache.org"]}
> curl https://$account.cloudant.com/_search_analyze –Hcontent-type:application/json –d '{"analyzer":"email",
"text": "rnewson@apache.org"}'
{"tokens":["rnewson@apache.org"]}
> curl https://$account.cloudant.com/_search_analyze –Hcontent-type:application/json –d '{"analyzer":"english",
"text": "running"}'
{"tokens":["run"]}
