System and method for performing optical character recognition on documents and for searching documents

A computer-implemented method for searching documents saved in a variety of language, comprising:

• receiving a keyword entered by a user using a first language;
• receiving searching criteria including searching a document in a second-language version;
• translating original documents into the first and second languages and storing a first language version, a second language versions, and the original documents in a database, wherein the first and second language versions are linked to the original documents;
• indexing each translated word of the first and second language versions, wherein each translated word of the first and second language versions is embedded with an index, and there are plural types of indexes in each of the first and second language versions;
• using the keyword and the searching criteria to search the documents, wherein the searching criteria are associated with certain types of indexes of the first and second language versions;
• searching related documents based on the certain type of indexes;
• and
• if the keyword and any of the indexed translated words of the first and second versions match, outputting the matched multi-language version as search results.

A search system for searching a document in a specific language, comprising:

• a user interface interacted with a user to enter instructions and select searching criteria;
• a computer, including a processor, a database, and a display, wherein the database stores computer-readable instructions, that when executed, causes the processor to perform:
• translating an original document into different language versions and storing the different language versions and the original documents in a database, wherein the different language versions are linked to the original documents;
• indexing each translated words of the original document based on predetermined criteria, wherein each translated word of the different language versions is embedded with an index, and there are plural types of indexes in each of the first and second language versions;
• performing an optical character recognition (OCR) on the different language versions to generate searchable PDF documents, wherein the searchable PDF documents includes the indexes embedded in the different language versions;
• receiving a keyword entered by the user using a first language;
• receiving searching instructions including search documents in a second-language version;
• using the keyword and the searching instructions to search among the searchable PDF documents, wherein the searching instructions are associated with certain types of indexes;
• searching related documents based on the certain type of indexes;
• and
• if the keyword and any of the indexes of the searchable PDF documents match, outputting the matched searchable PDF documents as search results.
