18. A machine-readable medium having stored thereon data representing instructions that, when executed by a processor of a capture system, cause the processor to perform operations comprising: extracting text contained in a captured object, wherein a content type of the object is determined and the content type is positioned in a content field of a tag associated with the object; generating a plurality of tokens from the extracted text; hashing the plurality of tokens to a plurality of bit position values; and creating a word index to be associated with the captured object by setting bits of a bit vector corresponding to the plurality of bit position values, wherein generating the plurality of tokens comprises tokenizing the extracted text using a context-aware parser, and wherein the context-aware parser uses a list of patterns associated with a content type of the captured object to sub-tokenize at least one of the tokens generated from the extracted text.
