Repeat The word And Use The Sentence.
I've been thinking that a lot of lang-8 members can write in Japanese fluently when I read your post, but when some people don't tend to use the same word and they use a wrong word like this.
私は、お店の名前を調べた後、行き方を調査した。(A)
or 私は、お店の名前を調べた後、調子する。(B)
調べる and 調査する have similar meaning, so (A) is good Japanese, but the nuance is slight different.
(B) is a wrong sentence. 調子（ちょうし) means condition.
I'd say "お店の名前を調べた後、行き方を調べた。"
Don't worry about repeating the same word.
If you use a word 20 or 30 times in the post, maybe I say "your sentence is childish" lol
And then when I can't understand what you wrote, I ask you "what do you want to say?"
Almost all people can explain it to me correctly and then I can understand what you want to say, so I want to tell you " the sentence you told me is very good!.
大変だとは思いますが、日本語の勉強がんばってくださいね。
