 Homo Search
 ======================
 
-The homogeneous search of helpful learnwares can be divided into two stages: semantic specification search and statistical specification search. Both of them needs ``BaseUserInfo`` as input.
+The homogeneous search of helpful learnwares can be divided into two stages: semantic specification search and statistical specification search. Both of them needs ``BaseUserInfo`` as input. The following codes shows how to use the searcher to search for helpful learnwares from a market ``easy_market`` for a user. The introduction of ``EasyMarket`` is in `COMPONENTS: Market <../components/market.html>`_.
