Phrase Indexing

A low-latency database analysis system comprising:

• a system access interface unit configured to generate data expressing a usage intent, the data expressing the usage intent indicating an unresolved data portion;
• and
• a relational search unit configured to:
• obtain the data expressing the usage intent from the system access interface unit;
• identify a phrase fragment based on the data expressing the usage intent and a defined phrase pattern, the phrase fragment including the unresolved data portion;
• identify an indexed phrase as a candidate phrase by searching a phrase index based on the phrase fragment, wherein the candidate phrase at least partially matches the phrase fragment in accordance with the defined phrase pattern;
• and
• output the candidate phrase to the system access interface unit, wherein the system access interface unit is configured to present the candidate phrase to the user as a candidate for resolving the unresolved data portion.

A method comprising:

• obtaining first data expressing a first usage intent, the first data expressing the first usage intent including a first unresolved data portion;
• identifying a first phrase fragment based on the first data expressing the first usage intent and a defined phrase pattern, the first phrase fragment including the first unresolved data portion;
• in response to a determination that a phrase index omits an indexed phrase matching the first phrase fragment in accordance with the defined phrase pattern, indexing the first phrase fragment in the phrase index;
• subsequent to indexing the first phrase fragment, obtaining second data expressing a second usage intent, the second data expressing the second usage intent including a second unresolved data portion;
• identifying a second phrase fragment based on the second data expressing the second usage intent and the defined phrase pattern, the second phrase fragment including the second unresolved data portion;
• identifying, by a processor, the indexed phrase as a candidate phrase by searching the phrase index based on the second phrase fragment, wherein the candidate phrase at least partially matches the second phrase fragment in accordance with the defined phrase pattern;
• and
• outputting the candidate phrase for presentation to a first user as a candidate for resolving the unresolved portion.
