inMeXes Help

The inMeXes incremental PubMed/MEDLINE expression search system enables you to search for English expressions appearing in MEDLINE titles and abstracts along with their frequencies and related research areas. English expressions here mean those having at least two words and appearing not less than ten times. It's just simple and very fast. After typing in four letters in the query box, you can obtain the search result instantly each time you type so that you can check English expressions easily and efficiently. A list of expressions that partially or exactly match a given query is shown in order of appearance frequency. Biomedical words are often long and complicated, and therefore search results of a part of it help you to remember the rest. This system is also helpful for researchers whose mother language is not English to write a paper in English. You can try by clicking here.



You can change the search behaviors using the pull-down menu just left hand side of the query box.


Sometimes you may get expressions that begin with many undesirable words such as be-verbs. In this case, you can filter them out by inputting a pattern into the Regular Expression Filter box. As this name indicates, you can use a regular expression.

For example, you want to know frequently used words other than be-verbs before the expression "associated with". Without filtering, the result includes many be-verbs. In this case, you may input this regular expression "(is|are|was|were|be(en)?|not) a". You can get this result.

Max display

You can change the maximum number of results shown using the pull-down menu. Either 20, 30, 50, or 100 can be selected.

External site

You can change an external site to which a result expression has a link. By clicking one, you can get following additional information regarding it.


You can obtain a permalink to a search result by clicking the "Permalink". This enables you to reproduce the result anytime by bookmarking it. Also, you can share the result with others by telling them it.
