sorting the search query prior to searching at least one of the indexed data structure and the lookup list.
8. The method of claim 7 , further comprising:
searching a first search expression of the search query in the indexed data structure; and
searching a second search expression of the search query in the indexed data structure upon determining that the second search expression is not located in the lookup list associated with the first search expression.
9. The method of claim 8 , wherein searching the second search expression in the indexed data structure upon determining that the second search expression is not located in the lookup list associated with the first search expression comprises:
identifying, in the lookup list, a pointer to a location in the indexed data structure associated with the second search expression.
10. A system for use in managing online help information in a data center, the system comprising a processor configured to:
gather a plurality of help information associated with a plurality of components operating in the data center, wherein subsets of the plurality of components are bundled together in products, wherein the plurality of components comprise embedded applications, wherein the data center supports the products, wherein the plurality of help information is comprised of online help documentation from a plurality of websites;
create an integrated repository of online help information by indexing contents of the plurality of help information into an indexed data structure of a plurality of search expressions, wherein each search expression is associated with a set of online help documents, wherein the integrated repository is accessible by each component, wherein the integrated repository is tuned for the embedded applications, wherein the integrated repository of online help information is updated dynamically in real time as a change in the plurality of help information associated with the products is detected; and
in response to a search query for an online help document, provide at least one help document relevant to the search query by searching the indexed data structure, wherein the plurality of websites would otherwise have to be individually searched for each of the plurality of components bundled together.
11. The system of claim 10 , wherein the integrated repository of online help information is updated dynamically in real time by updating the indexed data structure.
12. The system of claim 11 , further configured to:
detect a change in the plurality of help information; and
update the integrated repository of online help information based on the detected change.
13. The system of claim 10 , further configured to:
detect at least one of an addition of a component to the plurality of components and a removal of a component from the plurality of components;
based on the detection, determine whether the integrated repository online help information needs to be updated; and
based on the determination, update the integrated repository online help information.
14. The system of claim 10 , further configured to:
create a lookup list associated with the indexed data structure by parsing at least one online help document in the plurality of help information for locating search expressions likely to comprise a searched phrase; and
create a posting list associated with each search expression in the indexed data structure, wherein the posting list includes a set of online help documents and information regarding occurrence of the respective search expression in each online help document.
15. The system of claim 14 , wherein the processor configured to provide the at least one help document relevant to the search query by searching the indexed data structure is further configured to:
receive the search query, wherein the search query is comprised of a set of search expressions;
gather a set of matching posting lists by searching each search expression of the set of search expressions in the indexed data structure; and
sort the matching posting lists by ranking online help documents included in the matching posting lists based on relevance of each online help document to the search query.
