I don't think so. It's a slangy use of a Japanese word rather than two words.

沖縄の音楽は、独自の進化を遂げてきました。その沖縄音楽に欠かせないのが、「三線（さんしん）」。14世紀から15世紀の琉球王国時代に中国から伝わったとされます。民謡から現代のポップスまで幅広く使われており、沖縄の人にとっては、今でも馴染み深い伝統的な楽器です。

メイン, オフィス, and オブジェ exist as seperate entries in the database,, but when glossing a text containing メインオブジェ we are shown:
メインオフィス (n) headquarters; central office; main office; home office; home base [Partial Match]
Since i think that is a useful entry and should be kept,  i'd suggest adding an entry for メインオブジェ as well... :-)

Maybe obvious, but quite commeon (and the Text glosser currently mis-handles it.)
