Please Note:
• IBM’s statements regarding its plans, directions, and intent are subject to change or withdrawal without notice at IBM’s sole discretion.
• Information regarding potential future products is intended to outline our general product direction and it should not be relied on in
making a purchasing decision.
• The information mentioned regarding potential future products is not a commitment, promise, or legal obligation to deliver any
material, code or functionality. Information about potential future products may not be incorporated into any contract.
• The development, release, and timing of any future features or functionality described for our products remains at our sole discretion.
Performance is based on measurements and projections using standard IBM benchmarks in a
controlled environment. The actual throughput or performance that any user will experience will vary
depending upon many factors, including considerations such as the amount of multiprogramming in the
user’s job stream, the I/O configuration, the storage configuration, and the workload processed.
Therefore, no assurance can be given that an individual user will achieve results similar to those stated
here.

Query exactly the data that
your social application needs.
Get IBM analytics enrichments
in addition to base Twitter data.
Whenever needed, check
whether previously received
Tweets are still valid
(compliance).
Ingest, enrich, curate,
govern Decahose
data over time.
Receive & process
compliance events.

Queries
6
keyword Matches tweets that have “keyword” in their body. The search is case-insensitive. cat
“exact phrase match”
Matches tweets that contain the exact keyword sequence <”exact”, “phrase”,
“match”>.
"cats and dogs"
#hashtag Matches tweets with the hashtag “#hashtag”. #insight2014
from: twitterHandle
Returns tweets from authors with the preferredUsername twitterHandle. Must not
contain the @ sign.
from:alexlang11
followers_count:lower
followers_count:lower,upper
Matches tweets of authors that have at least “lower” followers. The upper bound is
optional and both limits are inclusive.
followers_count:500
posted:startTime
posted:startTime, endTime
Matches tweets that have been posted at or after “startTime”. The “endTime” bound
is optional, and is inclusive.
Timestamps have to be in one of the following two formats:
“yyyy-mm-dd”
“yyyy-mm-dd'T'HH:MM:SS'Z'”
Timezone is UTC
posted: 2014-12-1T00:00:00Z,
2014-12-12T00:00:00Z
The query language mimics the Gnip Powertrack query language, a subset of Powertrack operators is available. See documentation in Bluemix as we roll out more query
operators.
Boolean Operators
Operator precedence: “-” is stronger than “AND” and “AND” is stronger “than OR”. You can (and should) use parentheses to make operator precedence explicit.
Example: ibm twitter -(lame OR boring) searches for tweets that contain both the terms “ibm” and “twitter” but neither “lame” nor “boring”.
Query terms
All of the following query terms can be freely combined with the boolean operators introduced above, e.g. ibm apple followers_count:500
Operator Example(s) Description
term1 AND term2
cat dog
cat AND dog
#cutecat food
Returns tweets that contain both term1 and term2.
Whitespace between two terms is treated as AND, so the
operator can be omitted
term1 OR term2 #money OR broke Returns tweets that contain either term1 or term2
-term1 ibm -apple Returns tweets that do not contain term1

Count: /messages/count?q=QUERY
• Use to find out how many Tweets match a given query
