Use this search to find the paper you need quickly and accurately by selecting the category to search in and typing the keywords to search for.
Search Terms are the things that you enter into the search form that tell the search engine what things to look for in the papers at this site. The search engine immediately breaks the terms up into individual words and find all papers that have each word in them (a Boolean OR or NOT search would work differently). The terms should be entered as simple words (or numbers), not in quotations nor separated by commas or other symbols. Each one of your search terms should be keywords specific to a paper you need. Finally, remember to make sure your search terms are spelled correctly or the search engine will not find any matches (assuming the words are spelled correctly in the papers). You can check spelling online at WWWebster's Dictionary.
Since our search is designed to be lightning-fast and extremely accurate, it is programmed to scan every query and weed out words that are either too short to be of importance or words that occur so often in each paper that they become useless in narrowing down your request. Currently our search engine ignores any word whose length is less than three letters long (i.e. "the" is not ignored but "it" would be) and ignores any word that appears in over 80% of papers in that section. Anytime a word is ignored for either reason, this will be displayed at the top of your results and your results will be papers that have the un-ignored words in them.
By default, our search matches a series of words separated by spaces using the Boolean AND match type. This means that if your query is "vietnam war", the search will only find you the papers that have in them "vietnam" AND "war". This is the best match type in most cases, but if you have a special search specification, our search allows you to use the OR and NOT Boolean match types as well.
Papers that contain either the word "Russia" or "Communism".
Papers that contain the word "Russia" but not "Communism"
Avoid using very common words in your query as they will be ignored as stopwords.
All queries are parsed as case-insensitive so don't worry about case matching.
The best results are found by using one or several specific keywords in your query.
Please do not use quotes or other symbols in your query as they may hurt your results.
