This paper is based on an analytical study of modes of occurrence of keywords devoted to the subject Fermi Liquid, which is a specific domain under the broad area of condensed matter physics. Eight quantitative indicators have been defined and developed here on the basis of some parameters associated with keywords and keyword clusters. At least three keywords with a common phrase have been defined as a keyword cluster in this study. The numerical values of the indicators have been calculated for 2562 keyword-clusters, 916 keyword-couples and 4329 single keywords in all, though only top 20 keywords/keyword clusters are selected in decreasing order of numerical values of each indicator for presenting in this paper. The keywords were extracted from titles and abstracts of 6371 research articles devoted to the subject Fermi Liquid, which were collected from the bibliographic database of INSPEC and COMPENDEX, over the time span of twenty years (1985-2004). In total, 67 keywords/keyword clusters are presented here, which appeared 160 times within top 20 ranks (8*20=160) against eight indicators. A keyword cluster consists of at least three keywords and 665 keywords as studied here. The keyword-couples consist of two keywords only. There is no question of forming any cluster by the single keywords. The variations of numerical values of all indicators with the rank of keyword/keyword clusters are shown graphically. The mathematical functions followed by each variational pattern are also discussed.
