Powerful Search Mobysaurus itself is capable of handling 3 powerful search modes as listed below:(All support wildcards)

Search Modes

1. Look up in Root Words

If you look up “all” in root words, search results will return all root words that contain “all”, like “above all, after all, all around, all at once, etc.”

2. Look up in Any Occurrence

In this mode, the program will search the whole database for any occurrence of your queried word or words and list them, therefore it works a bit slower but returns much more comprehensive results.

3. Look up in Any Occurrence + Synonymous with

In this mode, the program will search the whole database for any occurrence of your queried word or words together with your designated synonym, and list the entries which simultaneously contain your query and the synonym. By applying wildcards in this mode, you turn Mobysaurus into a crossword puzzle solver instantly. For example, l??????” + “insect returns “ladybug” as one of the results, and “lap dog” (insect of a person).

Still remember the last time using a paper thesaurus? You check a root word in one page and never will have any idea if any better synonym might appear in another page under another root word. Even with a electronic thesaurus with every cross-reference, you are still facing a labyrinth of possibilities and endless mouse clicks. But with Mobysaurus & Moby Buddy, you know them all in a few seconds. Check them one by one or just some selections? It’s your choice alone.
